[Bug 12045] New: foobar2000 0.9.4.4 - window close lag

Summary: foobar2000 0.9.4.4 - window close lag
           Product: Wine
           Version: 0.9.57.
          Platform: PC
               URL: http://www.foobar2000.org/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown

I have some mysterious lag when working with foobar2000 version 0.9.4.4

When having windows (opened by foobar2k itself) open, like the file property
dialogue, or a file scan result window and I close this particular window
SOMETIMES (not always) I have some serious lag. Which means I click the
X-button, and at first nothing happens.

Now I can do different things:
1) Sometimes moving the mouse around triggers window closing
2) Sometimes dragging the still open window around triggers closing
3) Pushing the X a second time sometimes does the trick

I didn't notice this with wine-0.9.56, so it seems to be a regression. I'm
still trying to figure out some actions to always reproduce the problem, but
currently I'm not successful.

This problem is not bound to CPU usage. It also appears when the CPU is idling
at 99%.

Gonna try a bisect, but as I know no way to accurately reproduce it...

Someone with similar problems? Maybe not only fb2k?

Thanks,
Tobias
