I have identified the following issue and it seems to be related to the same phenomenon as this current problem. It appears to be a clear xterm.js issue, and I hope it will be addressed by the xterm.js team.

It seems this issue appears only in virtualization environment.

xtermjs/xterm.js#4665 was fixed in September 2023. Is this still a problem in more recent JupyterLab 4 versions?

@JasonWeill No, I’ve tested with 4.0.10, and I can confirm this issue was fixed.

@appleparan Thank you for the quick response! I'll close this issue, then.
