Screenshot/Video

Firefox ( also tested with new installation / different machine / vm etc.):

Other Browsers I tested (Opera, Chrome, Vivaldi, in this screenshot Edge)

Does this issue happen in VS Code or GitHub Codespaces?

• I cannot reproduce this in VS Code.
• I cannot reproduce this in GitHub Codespaces.

Are you accessing code-server over HTTPS?

• I am using HTTPS.

yeah this is happening with 4.5.0 but not 4.4.0 in Chrome, Safari, and Firefox. I just tried both side-by-side with fresh docker-based installs.
for what it's worth the 4.5.0 version also carries with it newer versions of the Jupyter extension. I tried downgrading to v2022.3.1000901801 with 4.5.0 but it didn't fix the problem. The Terminal also didn't work with 4.5.0.

[Emporea]

Can confirm that this bug doesn't occur on 4.4.0

But I dont get how it can only affect one browser.

[jsjoeio]

Is this a duplicate of #5335? Or are they somehow related?

[Emporea]

@jsjoeio
I don't know how they are related (atleast they share downgrading to 4.4.0 as a workaround), but this is definitly not a duplicate.

[jsjoeio]

Ah got it. Okay We'll investigate!

[mathematicalmichael]

@Emporea for me it is impacting all browsers I have installed.
@jsjoeio thank you very much for investigating! 4.4.0 is the first version where Jupyter notebooks actually function and it makes me so happy to finally be able to use code-server exclusively for my work.

Is this a duplicate of #5335?

No.

Or are they somehow related?

No, they are not.

[jsjoeio]

@mathematicalmichael hooray! that's great to hear.

We really need to add some e2e tests for Jupyter. I'm going to add this to the next sprint.
