visual corruption with GLAMOR and KWin of context menus
When right-clicking on the window decoration of a window which is rendered by KWin, the context menu always shows corruption of some sort. I've attached an screenshot of one such example.
My KDE is running with desktop effects on the the OpenGL 3.1 native renderer.
I'm not seeing this corruption with an Intel GPU and one of their custom acceleration schemes. But for as long as I've been using Glamor, I've seen this. I just forgot to report it. This might be a duplicate of bug 29873, but I can't tell for sure, because the referenced screenshot isn't available anymore. In any case, I'm only seeing the corruption in the context menus of the window.
My current stack (Debian testing as a base):
GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1)
LLVM: SVN:trunk/r226934 (3.7 devel)
