Re: [PATCH v2 0/1] MR10324: win32u: Fix deadlock when setting hdc_src to the window's self DC.

[Zhao Yi (＠Zhaoyi)]

- v2: When **hdc_src** is the **window's self DC**, Create a **compatible DC**, copy the contents of **hdc_src** to this **compatible DC**, and then use this **compatible DC** as the source for **AlphaBlend**.
