GNOME Bugzilla – Bug 644124
ctrl-alt-tab to panel causes flickering later
Last modified: 2014-08-04 16:10:59 UTC
If you ctrl-alt-tab to the panel, and then click out to a window, the menu/button that was focused when you left the panel will flicker every time you popModal() after that.
I can't reproduce the issue - should we assume that this got fixed at some point?
apparently
Nope. Hit Ctrl-Alt-Tab to focus the panel. Revert focus back to the window by clicking on it. Stare at the activities button, and then hit alt-tab. There's a hover state for a frame or two.

This got fixed a few years ago with my focus rework.
