Log Message:
Fixes bug with shader-transition effects (AnimateTransitionShader, Wipe, and CrossFade) when acting on targets that either have filters or are inside a hierarchy with filters. Fix was to capture the bitmap snapshot of the target without any of its own filters applied and to then use the ShaderFilter in conjunction with the target's filters during the animation.
QE notes: Probably need more tests in this area, now that we handle it
Doc notes: none

Lots to be excited about. BUT...Just updated to 8.1 on one of my computers to test it out...
Sadly, the following issue is NOT fixed for me. Is it with new projects only?  I haven't started a new project on 8.1 I've only opened an old project but the issue that I'm referring to which involves also a delay/freeze of anywhere from a few seconds to a MINUTE while the render bar goes from yellow to red and then back to yellow is still there. Boo.
On the list above...
Switching between sequences can turn the render bar red.
This issue is incredibly easy to replicate. I really do hope it gets fixed. Here are the steps:
1) Create two sequences with multiple short clips (the more clips the better)
2) Make sure GPU acceleration is enabled.
3) Add warp stabilizer to the clips in both sequences. Again, the more clips the longer the delay/freeze will be as the render bar goes from YELLOW to RED and then eventually back to YELLOW again.
4) Hit SAVE.
5) Now, toggle between sequences. You'll hit a short delay with a few clips stabilized and a LONG delay with lots stabilized. In my case this delay is around a full minute. The render bar will go from YELLOW to RED and then back to yellow...eventually.
6) Toggle back to the original sequence and the delay occurs again.
7) Once you've toggled between sequences and have gone through this delay, that's it, there is no longer a delay...UNTIL...(and here's the big kicker)...until the project is SAVED again. After that the issue returns when you toggle between sequences. Both saving manually and AUTOSAVING cause this issue. No way around it except not editing with GPU acceleration.
Not sure what the issue is...caching issue when saving maybe? Either way, it stinks and it's still there in 8.1. Big bummer.
Again, lots to be excited about with this release but I really was hopefully this specific issue was resolved.
Sigh.
