Looks like an animated cross-fade. The menus are visible in the intermediate frames with varying levels of opacity, one decreasing, one increasing. Looks intentional... Has anything else changed on your system? (In reply to comment #2) > Looks like an animated cross-fade.

I forgot to add that I don't see the blue color with UXA 2.18 at all. This also did not happen with earlier SNA, dunno exactly which version exactly (as I used snapshots). I'm pretty sure that 2.19 SNA already did not work. Ok, what is the theme? GTK or KDE? Composited WM? This is menu in thunderbird in KDE 4.8.3. So I believe GTK widgets in KDE. Composition/effects are turned on. I don't see it with Qt apps. I.e. with Qt widgets. Like menus in qtconfig do not expose this. Do you know which theme you are using for GTK+? Also are you using XRender effects or OpenGL? (If OpenGL, you don't happen to know a way to force KDE to keep using effects?) Ok, XRender desktop effects appear to be the key. commit 3c9759ef2ad755bbe720d4aa031ec67dbc3b7734 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon May 14 14:12:06 2012 +0100 sna/gen3: Fix pre-multiplication of opacity masks The return type for the multipliation was only 8-bits wide dating back to the time when the function just computed a single channel and didn't try to blend the output back into the argb pixel value. Inlining the shift into the function means that we need the output to be 32-bits wide instead.
