Large MRs UI performance: Sluggish loading/scrolling and extremely slow comment text input


i have this problem on Firefox and Chrome (Linux), and also on different gitlab instances (multiple private ones but also public):

In large MRs (means: Add e.g. a very large text file to an MR), the scrolling over the whole diff is very slow.
Clicking at a line in order to comment it opens the text input after a few seconds, and then the typing gives a very bad, slow experience: i can watch my text being typed in after i pressed the sequence of keyboard keys that leads to my intended text input.

Loading with a fresh firefox profile without extensions etc. changes nothing.

Has anyone experienced anything similar?

Yes, large diffs are very slow. I certainly haven’t found a way around that, except to close or mark as read some parts of the diff that I don’t need to see.
