Bug ID: 42643
           Summary: winecfg: Race condition causing winecfg window to
                    break out of emulated virtual desktop
           Product: Wine
           Version: 2.3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When Emulate a virtual desktop is enabled, winecfg sometimes displays as a
standalone window _outside_ of the emulated virtual desktop. The repro is
inconsistent -- sometimes I have to open winecfg 20+ times to repro, and
sometimes it happens back-to-back.

When it occurs, _sometimes_ the following appears in the console, but not
always:

$./wine winecfg
wine: Unhandled page fault on read access to 0x00000014 at address 0x7bc50d57
(thread 002d), starting debugger...
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr
0x7bc50d57

There is a secondary issue that arises when this race condition occurs. If the
race condition occurs, when the dislocated winecfg window is on a non-primary X
monitor, the winecfg window because unresponsive. It does not appear to respond
to mouse or keyboard input (escape key will close the window though). If I drag
the window back to the X primary monitor, it behaves normally again. In other
words, when the winecfg window is not contained within the emulated virtual
desktop AND is on a non-primary X monitor, the winecfg window is unresponsive.

I have repro'd this in 1.9.20-staging, 2.3, and the current master branch
(commit 4b14459). It occurs in both 64bit and WINARCH=win32.

Hello folks,

yep, marking as such.

The secondary issue is most likely a result of first one (partial init), it
should disappear when the problem is fixed.
