I couldn't reproduce this on our latest build (master 23c0cdb).

• shell open
• vertical scroll bars visible in the resource menu and main content area
• for both scroll area i could scroll using
  • manual use of scroll bar using mouse
  • cursor mouse over and mouse wheel scroll.

I'm using Chrome Version 131.0.6778.264 (Official Build) (64-bit)

@momesgin Could this be a browser thing? What rancher version, and ui build/commit were you using? Could you expand on what you mean by "Scrolling doesn't work"?

[momesgin]

@richard-cox I can repro this locally on the latest master, but only in Chrome(my version: 131.0.6778.140 - Official Build - arm64). Safari and Firefox seem to be working fine.

It's the vertical scrolling that doesn't work as soon as you open the shell.

In the recording, I'm trying to scroll vertically after opening the shell.

Version:

Same issue with the latest Chrome Version 131.0.6778.265 (Official Build) (arm64)

Just for some additional insight,

I was only able to reproduce this in chrome. Interestingly, when I first open the terminal I can continue to scroll without issue. However, after the terminal connects I'm no longer able to scroll even if I close the terminal and open a brand new.

It seems the root cause is having a z-index of 13(windowsManager: 13) on the terminal element that was added to fix another overlay issue by this PR. Whoever picks this up should make sure both issues are fixed in the end.

Rancher version: v2.11-af56e7fa886d35cb2f464422389c4a57e2f65a17-head

Scrolling with a shell opened is working as expected in this Rancher/UI build.
Navigating with the keyboard works too.
