Sometime hang here

I compiled Wine-11.1 from git and encounter a while window and spinning cursor
i.e. hang.
I found that wine-10.18 has no such behavior and so I can make bisection.
The result

----------------------------------
sergey@iMac wine-11 % git bisect good

    wined3d: Update the context DC from its swapchain if it changed.

    The context keeps a weak pointer to the swapchain, and the swapchain
    might be destroyed while are context still have a pointer to them.

    It's usually not causing issues because contexts will be refreshed with
    the new active swapchain before a present is executed. However, the new
    swapchain might be for the same window but might have a different DC.

    As we now borrow the DCs from the swapchains, we also need to check if
    the context DC needs to be updated.

Next step is revert this simple commit from 11.1 sources and test.
Yes!!! Now the Editor works fine.
Should mention that the bug appears 3 times from 4 attempts so not always and
may be connected to memory leaks in the game.
