Adobe Photoshop 2019/2020 gets freezes/stuck while common operations, after updating Windows 10 to version 2004.

After troubleshooting, confirmed that Microsoft Pinyin is causing this problem. I think it also exists with other built-in IME.

Reproduction

  1. Open Adobe Photoshop
  2. New or open an image
  3. Switch to MS Pinyin and stay on Chinese input mode
  4. Press and hold CTRL or ALT then click or drag with mouse on the workspace
  5. Photoshop keep freezing

Solution

Enable the compatibility option Use previous version in the Microsoft Pinyin settings.
