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

[Zhao Yi (＠Zhaoyi)]

Add some debug logs to the **UpdateLayeredWindow** function as follows:

![hdc1](/uploads/d8b526304cf9c5fd6a0ae36a620316c0/hdc1.png){width=900 height=148}

Then running test program test-UpdateLayeredWindow.exe, and deadlock,run result as follows:

![hdc2](/uploads/40a5892913b8b0d72590e59d4557356b/hdc2.png){width=900 height=183}

After applying my MR, run the test program again, and the window displays normally, run result as follows:

![hdc3](/uploads/085153accaac09d6c640a754cfdc284d/hdc3.png){width=900 height=372}
