Public bug reported:
Gnome-shell seems to be quite unstable recently. It seems one of the things
that started occuring the most the last few days is spontaneous crashes from
wine and guake, both programs I mostly use in fullscreen. When using guake, it
gnome occasionally becomes unresponsive to F12 (the un-hide button). And if I
press F12 several times quickly, Gnome-shell just spontaneously quits without
leaving any error or message in dmesg. When guake started getting flaky again,
I find this error repeating constantly in .xsession-errors:
Window manager warning: Log level 16: STACK_OP_LOWER_BELOW: window 0x2e00008
not in stack
Window manager warning: Log level 16: STACK_OP_LOWER_BELOW: sibling window
0x2e00008 not in stack
Also, when I tried running a fullscreen game using Wine, gnome-shell
spontaneously closed. Once again, dmesg didn't show any segfaults, but I
managed to pull an error from .xsession-errors that might show a clue to what's
going on:
Window manager warning: Log level 16: STACK_OP_LOWER_BELOW: window 0x3600008
not in stack
Window manager warning: Log level 16: STACK_OP_LOWER_BELOW: sibling window
0x3600008 not in stack
Window manager warning: Treating resize request of legacy application 0x4a00001
() as a fullscreen request
