Invisible underscores in File Browser

Since I have updated my Ubuntu to 24.04 LTS version there is a glitch appeared in Jupyter Lab file browser - all underscores in file/folder names are visually replaced with spaces. When you put the cursor over the folder/file name, the popped up window contains the correct name (with underscores). The screenshot is attached below.

I guess there is a compatibility issue between Jupyter Lab and Ubuntu. Is there a cure on users side or should I just wait for Jupyter Lab updates? And is this forum a place to announce such appearance errors or not?

OS and software versions:

  • Ubuntu 24.04.1 LTS
  • jupyterlab 4.2.5
  • jupyterlab_server 2.27.3

P.S. I am new to this forum. So don’t blame if this is not the right place for such discussion.
Glad to provide any details if required.

Do the files still open for you in Jupyter?
Do you have any browser extensions/plugins running and have you tried shutting them off and see if it continues?

My quick look at the JupyterLab issues page didn’t come up with anything that looks related; however, there’s always the possibility is it a new thing or that it manifests differently and it is reported in relation to that more. Or it’s some particular interaction on your system that nobody has brought up yet.

@fomightez thank you for prompt reply! Well, I turned off the only browser extension in Google Chrome - and the issue still persists. But I tried to launch JupyterLab in another browser (Firefox) - and there the names are displayed correctly.

So the issue is somewhere between JupyterLab - Google Chrome - Ubuntu.
I use mainly Google Chrome for JupyterLab because it provides correct behavior for coding when I switch languages. However, in the latest software update, I faced this insignificant issue.

  • Google Chrome Version 128.0.6613.137
  • Firefox Version 130.0.1

Looks like a font issue. We can probably alleviate it with CSS. Can you open an issue in JupyterLab repository? If you do not have/do not want to create a GitHub account let me know and I will open it
