--- Comment #23 from Rafał Mużyło galtgendo@o2.pl --- ...all those years and I've never noticed.
Leaving a future note: I just found display settings applet in the wine's control panel; I've never really looked there before, only remembered that it had a input calibration applet and little else - while that's still true, the display settings applet might be able to test/confirm certain things once the bug triggers again. See you afterwards, if I'll remember this then.
