Rippling on screen when scrolling

Just noticed a more pronounced ripple effect on screen when I scroll down a page.
Using OS X Version 10.10.2 with iMac 21.5 graphics card is GeForce GT750M with 1024MB
Anybody any views on this?

Ripples in screen when scrolling up or down, therefore terrible viewing has not been fixed with 4.0.1. Tell me when it is fixed otherwise I will use 3.6.17!

4.0.1 still has not fixed the ripples in the middle of the screen. When I fix it I will use 4.0.1, otherwise I will use 3.6.17
The ripples really give one a headache, literally, not figuratively, so it is very important.

Unless Apple replaced your battery, and it appears they didn't, you're pretty much on your own now. Have you tried going back to whoever replaced your battery? That's gonna be your only choice now, because if a third-party replaced your battery, Apple won't touch your phone now.

Jumbled line across screen when scrolling

Since the past few days my IMac has a jumbled line of type across the screen when scrolling either up or down. It is not in the same place vertically but moves higher or lower seemingly random. Any ideas?
Thanks, Paul

I assume we're all talking about the problem mentioned here:
http://apcmag.com/appleslatest_notebooks_plagued_with_graphicsglitches.htm
I'm seeing it on a 15" MacBook Pro purchased shortly after release last year. Web pages in Safari sometimes become corrupted (missing bits of lines) when scrolling, especially using the two-finger method, and flash videos and various animations flicker annoyingly.
Given the range of hardware it has been reported across (and the number of people who have had bits of their Macbooks replaced by Apple only for it to recur), it looks like it's a software problem, and I find it more than a little frustrating that Apple don't publicly acknowledge it yet (if they do, I've found no mention of that, just lots of comments from people affected by it).
Is there a canonical thread/bug that you can register for to be notified when Apple finally fix this?
It's a continuous annoyance at the moment.

How can I stop the ripple across the screen when scrolling down since I upgraded my Mac to Firefox 4 ?

Since I upgraded to Firefox 4 I am getting a horizontal ripple across the data when scrolling down, which is very disruptive and uncomfortable. How can this be corrected. I am using an IMac with Mac OS X 10.6.7 ?

Same problem on Imac with updated software. Had problem in earlier versions and changed key : <key>CGDisableCoalescedUpdates</key>
<true/> to false and that resolved the problem. It helps somewhat with Firefox 4, but not enough. Is this just a Mac problem or are PCs having the same problem? This may be enough for me to switch browsers or go back to 3.6.

Screen vibrates/twitch while scrolling websites and in mail (only top part of screen) when scrolling pdf it seems to be ok.

Screen vibrates while scrolling websites and in mail - scrolling list of e-mails. Only top part of screen is when scrolling .pdf it seems to be ok. any suggestions?

Try a smc reset:
http://support.apple.com/kb/HT3964
follow instructions for a battery you
not remove yourself
Try a pram reset
Power off, power back on holding the folowing keys:
OPTION COMMAND P R
Continue to hold these keys till you hear the start chime 2 times then release. Reboot.
If you still have the issue bring it in to an Apple Store Genius bar for a a freevaluation, you may have a hardware issue.

Screen ripple effect when scrolling after installing Mavericks?

Since downloading Mavericks some three weeks ago, my screen ripples (wave effect) when scrolling.
Dominic kindly responded a short time ago with the suggestion it could be Autocad update related.
All traces of Autocad wiped from my machine but still experiencing this ripple effect when scrolling.
Beginning to wish I had not updated to Mavericks.
Help!!!

Mine too have this on my new MBP ( September 2009).
It's more evident in Safari, but show also in finder while scrolling. It is not related to font antialiasing because enlarging page text in Safari (cmd +) the blurry effect is still there.
I'm very disappointed of lcd screen quality, too much fatigue to eyes.
Could be considered a screen hardware defect?

Issue with hidden subforms and fields becoming visible when scrolling

Hi all:
Was testing an XFA form on a 13" macbook air when I noticed something odd: Page 1 (which had a presence of "hidden") became visible on-screen when scrolling down Page 2, which was set to visible. For lack of a better description, Page 1 "bled through" the currently visible page but then disappeared after the scrolling action was complete.
Here was the sequence:
- FYI: 4 pages in the form; only one page is visible at a time. When the document opens, Page 1 is visible and all the others are hidden.
- Opened on a MAC with Reader XI
- Answered questions on Page 1 and clicked a "next" button which set Page1 to hidden and Page 2 to visible;
- I zoomed in for a better view on Page 2 (again Pages 1, 3,4 are all "hidden" at this point)
- When I placed two-fingers on the track pad and scrolled down, the bottom of hidden PAGE 1 was revealed during the scroll, not the bottom of Page 2.
- When I lifted my fingers OFF the track pad, the bottom portion of Page 1 that became visible while scrolling disappeared and was replaced by the bottom of Page 2.
Same thing happened with pages 3 & 4. If I zoom in and scroll up, down, left or right using the track pad, Page 1 (even though it is set to hidden) "bleeds through" during the scroll and then disappears when fingers are lifted off the track pad.
I've done some testing and it happens on Macs running Reader. Mac with Acrobat and PCs with either Acrobat or Reader appear to be fine but not finished testing.
Made a simple working example. Again, be sure to open on a Mac with Reader if you want to see it happen. https://www.dropbox.com/s/jnf4uxntuzvrk7p/bleed%20through%20tests.pdf?dl=0
Has anyone else experienced this?? How can we stop it from happening as it is extremely confusing to the end-user to have two different pages mixing together when scrolling.
Thanks much.
Brian

Just reaching out to the community again on this. Any thoughts or similar experiences?
FYI, I tested the new Reader DC for this issue yesterday and it's still there. Hidden pages still bleed through.

Screen display is blurry or ripple effect when scrolling

I have a 15 inch 2.53 Pro and when I am in Safari the screen has a horizontal ripple effect across the screen when I am scrolling. This is slightly worse when I use the vertical scroll bar vs. two-finger scrolling. The overall effect is that the screen is slightly blurry and hard on the eyes to read until the scrolling is stopped. This is a new machine and I have just installed Word suite for students. Any suggestions? I have an iMac that is a few years old and this does not happen on it. Thanks.

Display ripples when scrolling ANY types of pages

This is driving me nuts. And giving me headaches. And making my head spin.
My MBPro 2.4Ghz with infamous Nvidia 8600M GT 256MB graphics card is the culprit. A real letdown compared to all the Macs in general, and the portables in particular, that I've used over the last 20 years.
As others have reported here, there is a MAJOR issue with "rippling" lines of text when scrolling web pages. But I am getting the same thing when scrolling ALL types of pages: web, text, spreadsheets, etc.
It happens both on the MBPro screen and on an external monitor.
It happens when scrolling with the trackpad or with a USB mouse.
It happens at all times.
And, if this is possible, it seems to be getting worse. It's almost at the point where I have to TAKE MY EYES OFF THE SCREEN if I have to do any scrolling. If not, by the end of the work day, my head is spinning, my eyes are dead tired, I'm going cross-eyed and, more times than not, I've got a headache from all the "visual effects".
I took my MBPro to an Authorized Apple Technician, to see if it had the defective Nvidia graphics card. I'd done a reformat and fresh install of 10.5.7 the night before.
The Nvidia test software, on an external HD, showed that I don't have a defective card.
Not a bid deal in the end, as they would have just installed the SAME type of graphics card and logic board.
I convinced the Apple Tech to use my MBPro for a few minutes, just to show him what I meant. He said he was surprised to see the ripples, that he'd never really focused on that in the past. But they were definitely there, and he wasn't able to say that it was "normal", as he really wanted to do.
He said he thought it might be a problem with the NVIDIA DRIVERS.
He then went onto his 24" iMac with Nvidia graphics card and, lo and behold, he had THE SAME RIPPLING while scrolling longer web and text pages.
This made him more convinced that it must be "imperfect" Nvidia drivers in Mac OS 10.5. And he said the only thing to do was hope that Apple and Nvidia get these drivers perfected and thoroughly tested in the near future, either by specific update or IN SNOW LEOPARD.
What's frustrating is that I have NEVER had this problem with either our iMac 20" Core Duo, which has an ATI graphics card, or our Macbook Core 2 Duo with GMA 950 Intel chipset. That is, with much older, less powerful Intel Macs, but ones that DON'T HAVE NVIDIA graphics cards.

I call it more of a flicker, but I also experience this issue with a MBP (led backlight). It is not browser dependant, but as Safari scrolls smoothly, it is much more apparent with this than other browsers.
Here is a perfect example, watch the sidebars on this page while scrolling :
http://www.theautochannel.com
It's also particularly bad with this site (apple discussion board), and others with high contrast text, the text flickers/ripples very badly This never happened with my Powerbook display. Is this an issue or simply inherent with these displays. Personally, it is giving me headaches when scrolling through large amounts of text (which I often do for work), and rendering this laptop virtually unusable for me.
I'm surprised to find very few others complaining about this phenomenon, perhaps I'm not describing the issue well with my search terms. Has anyone heard of a solution?
Thanks

Starting random apps and screen flicker when scrolling

My Touch 2G suddenly started to launch random apps without me touching the screen. Besides starting random apps the screen flickers when scrolling. Any body have experienced the same? It started about 1 month ago and I have always taken good care of it. I have tried every possible thing I can think of when it comes to software. Full restore, jailbreak, full restore, back to factory, back to earlier versions of IOS, but no luck. It is pretty persistent. I am sure it is hardware related and don't mind paying to have it fixed. I tried two repairshops already and they were not able to recover the reason for the malfunction. I wonder whether there is anybody who has experienced the same or even knows what is wrong?

Hey Kimwaldal,
Thanks for using Apple Support Communities.
Sounds like the devices are opening things on their own. You may want to follow this article to make sure the screens are working correctly.

You have the accessibility VoiceOver feature turned on.
Triple click the home button and try going to Settings>General>Accessibility and turn VoiceOver off. You may have to use three fingers to scroll the screen to get there. If problems see the following for how to turn off via iTunes:

Adobe screen going black when scrolling...?

We do PDF replacements within our workflow all day long and just recently started having an issue. After doing a page replace (often almost the entire document) of a pdf with another pdf, we have to go through and check that the bookmarks are accurate. When scrolling through, there's one user that the screen sometimes just goes black on. They have to close the document and reopen it. Then, when it goes black again as they scroll through, they have to close and reopen it again. Very frustrating and time consuming.
Using Adobe Acrobat 9 on a Windows XP (old, I know) environment. We unloaded the software and reloaded it. Then the computer was rebuilt as that did not fix the issue. Issue still remains. It's only on one computer, regardless of what user is logged in.
Thoughts? Options?
Thank you!

IPhone screen shakes violently when scrolling/dragging pages

Hi,
I have a 1.5 month old black 32g iphone 3GS (3.1.3) that has recently started experiencing a sporadic problem with the screen. When I'm dragging/scrolling on the screen (either scrolling through emails, or scrolling on a webpage, or even dragging a photo around), it begins to shake up and down very quickly and violently, and sometimes jumps around to different parts of the page without me doing anything other than just dragging like I always do.
The problem seems to go away after a while, but will come back randomly, sometimes within a few hours, or sometimes not until a few days later.
This has been happening for about 2 weeks now. The screen is in perfect condition, no scratches, no dust underneath it, so Im baffled about why this is happening.
Is anyone else experiencing this?

I'm having the same problem with my iPhone 3gs. I'm currently at a genius bar, and they need me to replicate the issue inorder to service the iPhone. Anyone have an idea as to the cause of this, or how to replicate it on demand or the apple genius to see? I've had mine for nearly a year and am afraid tha my warranty will run out before I can have apple fix the issue. Any help will be greatly appreciated!

Ripple effect in Safari browser when scrolling pages

When scrolling through a web page in safari using my new iMac Core Duo 17" there is a "ripple" effect in the middle of the page I'm scrolling through. This happens when I use the mouse to drag the scroll bar on Safari. Happens no matter what web page I'm on. This didn't happen on my iMac G5.
Any else have this problem?

The threads I saw on this are locked... I had no problems with anything UNTIL the 10.4.5. update - now I have the Safari "ripple effect" on almost every web page. I have to select / highlight the "rippled" portion of the page in order to view it properly...Wonder why this happened to my machine after the update? The update seems to have fixed this problem for others...
