Re: [PATCH 0/1] MR10324: win32u: Fix deadlock when setting hdc_src to the window's self DC.

[Zhao Yi (＠Zhaoyi)]

There is a test program used to test the deadlock issue caused by setting **hdc_src** to the **window's self DC** when calling the **UpdateLayeredWindow** function.

demo: [test-UpdateLayeredWindow.exe](/uploads/96eeece57b90c76daf22c8293f4cb718/test-UpdateLayeredWindow.exe) [test-UpdateLayeredWindow.cpp](/uploads/ebdf27dc9a9fea676fc10b11c8e14a12/test-UpdateLayeredWindow.cpp)
