--- Comment #2 from Fabian Maurer dark.shadow4@web.de --- Created attachment 56967 --> https://bugs.winehq.org/attachment.cgi?id=56967 +relay log that shows what happens inside WM_MOUSEMOVE
Attached a log for what happens from one WM_MOUSEMOVE to the next. Don't quite understand why the DC seems to clear on windows, but not on wine.
