Click and drag text corruption

[rvalieris]

I'm seeing text corruption on xterm embedded on jupyterlab and vscode, and I can reproduce it on the xtermjs.org website:

However, I tried to run the xterm demo locally on the same browser and I can't reproduce it there, is there anything I can do to debug this ?

I also tried this on another linux machine, however I was unable to reproduce it there on the xterm website.

Details

• Browser and browser version: Chromium 115
• OS version: Ubuntu 22.04 LTS
• xterm.js version: not sure, on the demo I tried versions 5.0.0 and 5.1.0

Steps to reproduce

1. refresh the page
2. switch to a few other tabs
3. switch back to xterm
4. click and drag text selection on the terminal

I think I've seen this reported before and it's specific to Linux.
