After updating to Bridge 12.0, the XMP files are flashing when I move to a directory containing RAW files. The flashing eventually stops, but the XMP files are continue to be shown. "Show Hidden Files" is not selected, and selecting and unselecting, makes not difference. It must be a preference setting, but I can't find it.
I have been in contact with Adobe support because I encounter the same issue. I have discovered that when I rename the sidecar files from .XMP to .xmp the problem disappears and everyhting is normal.
I just discovered a strange thing that might help troubleshooting this: I opened an older folder with Bridge 12, containing CR2 and .XMP files. The problem occurs: the fimstrip is flickering, flashing, blinking, or how you would call it. I close Bridge 12 and open Bridge 11 to view the same folder. Everything looks normal. Then I close Bridge 11 and open Bridge 12 again, to look at that same folder. Everything looks normal!
I am experiencing the same problem. I'm on version 126.96.36.199. The problem happens in any folder that contains .arw and .xmp files. I'm willing to provide any info that is required to determine the cause.
Saw your post and did the same, seems to have stopped the problem. Luckily most of my files were lower case.
Note I did not say solved the problem since I don't consider this really a solution.
A new version of Bridge was released (12.0.1)
Apparently, the flickreing was fixed.
New update fixed mine also. Thanks Adobe.
My problem is now fixed. Thanks Adobe.
