Bug ID: 58044
           Summary: Realm Grinder freezes/crashes after a very long run
           Product: Wine
           Version: 10.4
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv

Created attachment 78299
  --> https://bugs.winehq.org/attachment.cgi?id=78299
output of two failed runs

This I strongly suspect is a regression, yet I can't really pin down the time
when this started happening. The problem happens with little to no human
interaction, yet the timeframes make it unreasonable to actively reproduce.
I suspect it started around 10.0 release, but with a -/+ 2 months margin (so
close to useless).

Anyway, what's the problem ?

If Realm Grinder is run for long enough (but 'long enough' here is measured in
*days*), it tends to eventually either freeze with a completely black window or
crash with an X server error.

The attachment has output of two such runs, second chunk is when it just froze,
the first when it crashed.

'fixme:d3d:swapchain_blit_gdi Using GDI present.' at the end of both seems to
be the moment the problem triggers.

It seems to be some kind of a resource leak, but it doesn't affect any other
apps running besides it, not even those run by wine.

No user action is really required to trigger this - I've seen it freeze after a
desktop switch, I've seen it crash when the window was just displayed, but not
really interacted with.

(Realm Grinder here is still at v4.2.27.0, though I'll likely update it shortly
for Easter event)
