@Polve can you still reproduce this with Nextcloud 28.0.6, richdocuments app 8.4.2 and Collabora Online 24.04? I ran into the same problem before, but was not able to reproduce this any longer, so I wonder whether this got fixed in the meantime.

Tried right now with nextcloud 27.1.9, nextcloud office app 8.2.10 and coolwsd 24.04.3.1, but the problem persists

There were related fixes in richdocuments (nextcloud office) app release 8.4.2, which requires Nextcloud 28. If you can upgrade, would be great to get a confirmation if this solves the issue.

I upgraded to nextcloud 28.0.6 and rich documents 8.3.7 and the problem is still there :-(

I will try to upgrade to NC 29

[Polve]

Ok, tried also with NC 29.0.1 and richdocuments 8.4.2: same problem, unfortunately :-(

But at least you forced me to upgrade :-D

Thanks for the feedback @Polve. Could you provide clear reproducer step by step instructions? I was unable to reproduce it with dark theme in browser set, bright theme in browser and dark theme in Nextcloud, and bright theme in browser and dark theme in Collabora 🤔

I don't know how to make you reproduce: I run two installations that always worked fine until that upgrade, and in both installations I have the same problem.
Maybe it's something special about my configs, but they should be pretty standard.

I can just tell you that I have the dark theme both on my (ubuntu) desktop and firefox, and the problem is there.

To reproduce I suppose I should try a new installation from scratch but this could take me some time.
