Not only caused by QQ , if anything try to copy image data to clipboard then WSLg crashes.

@hideyukn88 I'm using Windows QQ to take the snapshot

@NijiharaTsubasa and @sanjitako, would you please update WSLg to version 1.0.26 at https://github.com/microsoft/wslg/releases/tag/v1.0.26, and send us dump files at /mnt/wslg/dumps? thanks!

I've been experiencing a related version of this problem. I'm not actually using WSLg, it's just running as it was installed as part of the Windows 11 upgrade.

When I take a screenshot with Greenshot (1.2.10.6) and copy it to the clipboard, WSLg appears to die and get restarted. This shows in process explorer as mstsc processes starting and stopping every second or so:

This also causes system tray icons to flash once a second, and sometimes grabs focus. Clearing the clipboard (or copying some text to it) makes the problem stop.

Dump: core.zip
Log Snippet: weston-log-snippet.txt (this sequence of logs repeats with each process crash)

Additional comments:

• Cannot reproduce by copying from Snipping Tool, Paint, paint.net
• Not every copy from Greenshot causes the problem, but repeatedly copying the same image from the editor has always caused the issue within 2 or 3 copies
• With docker desktop running, I have 3 WSLg hosts, copying an image from greenshot doesn't always affect all of them - repeatedly copying the same image might affect another one. I can easily get all 3 hosts affected.

I have this issue too, seems the clipboard sharing feature crashes mstsc.exe when QQ screenshot or some other tools copy images into the clipboard. But Win+Shift+S works fine.

@richardlawley, @liyafe1997, this issue should be fixed by newer release of WSLg from aka.ms/wslstorepage, please update, thanks!
