1152468 - Graphical corruption in the tabbar/awesomebar on switching between tab groups

Status: RESOLVED DUPLICATE of bug 1146195

(Firefox :: Theme, defect)

STR
Have a couple of tab groups with O(10) tabs in them.
Restart with session restore enabled.
Switch to Panorama and select a different tab group.
There are drawing errors in the tabbar/awesomebar (see screenshot).
These will go away only if the window is minimized and restored.

My guess is the time it takes to open a tab group which hasn't been viewed before the first time in a session plays a role here, as sometimes it looks like the previous active tab from the tab group one is switching away from is partially drawn even after the switch.

This is a regression in 39 - it didn't happen in 38.

aleth, can you find a regression window using mozregression? http://mozilla.github.io/mozregression/

Unfortunately I no longer have the profile/state with which I could consistently reproduce this. I tried creating a similar profile but the reproducibility was too unreliable to be able to find a useful regression window in a reasonable amount of time. I may try again when I have more time to experiment with the kinds of tabs added etc.
