https://bugs.winehq.org/show_bug.cgi?id=44030 --- Comment #2 from Stuart Axon <stu.axon(a)gmail.com> --- I've been trying to work out how to reliably trigger - it, but haven't worked that out. At least, it's easy to trigger - you just don't know when (theres like a one in 4 chance) I noticed, that every time it triggers there is this messaged logged: 0072:fixme:msg:pack_message msg 14 (WM_ERASEBKGND) not supported yet Once it has been triggered, then I seemed to get this message every time I change something. - E.G. Just now I was trying to trigger it: I kept toggling "Allow the window manager to decorate windows" and hitting apply. I couldn't get it to trigger the message was not logged. Then I changed the DPI, hit apply and toggled the bug. The message was logged. I went back to toggling "Allow the window manager to decorate windows" and now, every time I toggle it the message was logged. You can see things redraw at the point where the bug is triggered, and not the rest of the time. It seems less likely to trigger when you slowly click - *press and then wait a bit before releasing the button...) but I still managed to trigger it this way. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
