Lightroom CC reloading on editing TIF files

Question

OK - another little Lightroom CC item I did not experience in earlier versions.
Library catalog settings set to record data to XMP file, as is my standard operating procedure.  NEF raw file edits proceed as normally.  However, on editing TIF files, such as those created externally via Silver EFX or what have you, LR constantly "reloads" the image after every edit (so it seems), and does not keep any of the edits made to the image on reload.
The workaround I found is to turn off recording data to XMP, however I prefer to have XMP data separate from the LR catalog.
Anyone else experiencing this issue?

Answer 1

Thank you! Yes, I have exactly the same problem. Since upgrading to LR6, touching almost any slider in the Develop module would cause the image to "reload". Worse, it would often "forget" my previous develop edits: even though they were listed on the History panel, they would no longer have any effect.
Great catch, noticing this was just for TIF files!  I didn't make that connection. But as most of my edits involve a round-trip into either PS or Nik, I was almost always editing TIF files. As you suggested, I've disabled "Automatically write changes into XMP" in the Catalog Settings - and now it once again works properly. My first guess was that this had something to do with GPU rendering, but disabling the GPU had no effect on this problem.
This is potentially more than just an annoyance. As mentioned, such a "reload" event would often lose ALL of my previous edits (even though they were still listed in the History panel) and reset the image back to the starting point. That's actual data loss!
