The shadow flicker of Microsoft Chinese Input Method #282938
Description
Type: Bug
I first noticed this issue starting from version 1.106. It manifests as the irregular flicker of the input method's shadow when typing Chinese in VS Code, and I will attach a GIF animation later in the text. This problem has not occurred in any other software and currently only appears in VS Code. Visually, this makes me quite uncomfortable, especially when I'm editing Markdown or Typst documents.
Unfortunately, this issue is completely invisible in the recorded GIFs, so I can conclude that it is jointly caused by Windows, Microsoft Pinyin Input Method, and VS Code, with the first two likely bearing greater responsibility. The symptom is as follows: the originally dark shadow beneath the input method suddenly fades and flickers several times, and this happens with every input. However, this problem only occurs in VS Code. If there are other users who have encountered the same issue, it can verify my claim (I have experienced this problem on three Windows computers).
