Well to continue on this, I’m not only talking about LibreOffice. For me it’s all qubes applications. I assume Nika has similar issues since we run on the same hardware. So I would say ignore LibreOffice and think of this as a more “global” issue.
Tried most things to get better performance, nothing so far. But @OvalZero did have a point in that our setup does not use the GPU for rendering, while @OvalZero has no issues and is using GPU in dom0 (I think, don’t exactly remember). This is one thing that might cause this, but not confirmed.
I would not get to hung up on LibreOffice especially since the person who created the thread mentioned “new to Linux”. They just don’t know how to talk the lingo, all they notice is issues with the apps they mainly use.
Also would recommend reading the full thread here: LibreOffice on Fedora 41 lags and is sometimes unresponsive - #48 by JocularMarrow . It gives some more context, I think I hinted at more of a global issue. Will try to make it clearer next time.
Funny thing is that the only app that runs well is Mullvad browser, not sure how or why but better then nothing. Still really really struggles with js/css, did not expect that good performance but it’s kinda bad ngl. But typing in editor is impossible, takes like 1 sec before my input catches up with what is being displayed. For me a real blocker to do any development work at all. And yes vim/neovim works fine but I like my zed/vscode (vscode on qubes since zed kinda wants a gpu).
CPU usage not high, would say lower side. Also tried giving more/less RAM, ballooning/not ballooning and played around with cores. Even tried with smt=on (don’t try this, opens up attack surface).
