Re: [PATCH v3 0/4] MR8958: win32u: Fixes for the OpenGL drawables mess.

[li xiao (＠xiaolizai)]

When I merged this request and submitted win32u: Don't store the window OpenGL drawables on the DCs.:, I encountered a deadlock while running a software using wine: 01 a0:err:sync:RtlpWaitForCriticalSection section 00007F4A4ACC5570 "?" wait timed out in thread 01a0, blocked by 0134, retrying (60 sec). Before the merger, it's ok.

After this submission : **win32u: Don't store the window OpenGL drawables on the DCs.The lifecycle of opengl_rrawable is no longer related to DC,Why is there still**

```c
struct opengl_drawable *opengl_drawable
```

**in DC?**
