--- Comment #8 from Rémi Bernon  ---
Thanks, the dbghelp messages usually indicate that some thread has crashed and
that probably explains the deadlock. There's no obvious crash indication or
clear call either yet.

Lets add +seh,+opengl,+d3d,+dc,+gdi,+bitmap,+loaddll to the list of debug
channels if you don't mind, to try to get a bit more context. (so
WINEDEBUG=+timestamp,+pid,+win,+msg,+message,+x11drv,+event,+wgl,+bitblt,+seh,+opengl,+d3d,+dc,+gdi,+bitmap,+loaddll
)
