Lightroom CC 2015.5: Strange behavior when moving vignette sliders

I get a strange behavior while moving the vignette sliders in the Effects Panel on my 2011 iMac. It's hard to describe, so I made a screencast of it:

It's most visable with Fuji RAW-files, especially from the X-Pro2. The issue disappears on my iMac as soon as I deactivate OpenGL by unchecking the "Use Graphics Processor" box in Lightrooms preferences.

On a MacBook without OpenGL-Support (Intel HD 3000) there's the exact same issue.

So it seems like it’s not OpenGL, that causes that problem.

No problems like that at all with former versions of Lightroom CC

Any ideas how to fix it or ist that a bug?

Hi BDX. Does this happen with all files or only specific ones?

It may help if we could see your Lightroom System Info in the state when the issue is happening. Directions for sharing your system info from Lightroom:

I have exactly the same issue once updated to LR 2015.5 on an iMac 2011. Seems to be a bug introduced with the latest version. Once disable the UGP check box it's gone, but obviously the support for UPG got broken now.

Best regards
