Description: For some time already, all libreoffice programs started to run really bad (not responisve, etc.). Some time ago, I've heard about the skia reneder and though if I could test it. It looks all I had to do was remove the libreoffice-qt5 or libreoffice-gtk package which my problems by providing another renderers. PS: It is interesting because it runs smoothly on my PC. Might be because I have a dedicated gpu. Steps to Reproduce: I haven't been able to find another person with the same problem. 1. Install libreoffice-qt5 (name of the package on opensuse tumbleweed) 2. Start any libreoffice program (writer, draw) and open a simple file (or create a couple empty pages) 3. Try to scroll or just the program at all Actual Results: Everything lags. Scrolling is absolutely not smooth. It scrolls like I am on a computer from 1990.

Thanks for the report. A couple of questions: - What kind of display do you use? High DPI / large resolution? - Please paste here the version information from the Help > About LibreOffice dialog _for when it lags_ (I assume you pasted the info for when it does not lag in comment 0). I see you use Wayland, so potentially related reports are bug 160140, bug 153111 and bug 141578.
I'd like to correct myself as well. I does not run smoothly on my pc. Not at all actually. It runs worse than on my laptop (sadly i cannot get you logs from my pc right now because I nowhere near it). Here is the information. I have a 90hz 2880x1800 screen on my laptop and I use 135% scaling in plasma settings (but this does not affect the programs performance). Libreoffice Version: 24.2.2.2 (X86_64) / LibreOffice Community Build ID: 420(Build:2) CPU threads: 16; OS: Linux 6.8; UI render: default; VCL: kf5 (cairo+wayland) Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded
It seems it runs smoothly when using x11. If you need someone to test or to provide certain logs, I can do that. This can now be flagged as a duplicate, I think.
I think the best match is bug 152911 (kf5 cairo+wayland, scaling on, large display). Thank you! *** This bug has been marked as a duplicate of bug 152911 ***
