Description: With SAL_USE_VCLPLUGIN=gen libreoffice, LibreOffice Writer runs super fast without any issue. Steps to Reproduce: 1.Run LibreOffice on PopOS 22.04 (Gnome environment; GTK3) 2.Bigger documents with many tables can hardly be edited as keyboard input becomes extremely slow. 3.It must be related to VLC=GTK3 Actual Results: LO Writer is almost unusable with GTK3. Same happens on my system with kf5. It may be related to Nvdida driver (version 525.60.11) Expected Results: When I run LO with SAL_USE_VCLPLUGIN=gen libreoffice, it works without any issue. Reproducible: Always User Profile Reset: Yes Additional Info: Version: 7.4.3.2 / LibreOffice Community Build ID: 1048a8393ae2eeec98dff31b5c133c5f1d08b890 CPU threads: 16; OS: Linux 6.0; UI render: default; VCL: gtk3 Locale: de-DE (de_DE.UTF-8); UI: de-DE Flatpak Calc: CL
Do you have any accessibility tool enabled? If yes, could you disable them just for the test? Indeed, contrary to gen rendering, gtk3 and kf5 use accessibility part. It could also be due to Skia or graphic driver, could you apply advice from the link https://wiki.documentfoundation.org/QA/FirstSteps#Graphics-related_issues_.28_Skia_.29 ?

Thanks a lot for your answer. I have disabled all accessibility tools, but the issue still occurs. Regarding the graphic driver, I get "UI-Render: Standard" when accessing the "About info". I have also tried to disable "HiDpi daemon" of Pop Os, but there is no difference - the lagging is still there. I use a 4k screen, maybe it is related to that.
Thank you for the feedback, let's put it back to UNCONFIRMED since I don't have more questions.
As Pop! OS is based on Ubuntu, do you use Wayland with GNOME? You can see if LibreOffice is a Wayland window with: https://bugs.documentfoundation.org/show_bug.cgi?id=100156#c1 And do you use a scaling factor for your display or are you at 100%?
Cause is likely the 4k screen. *** This bug has been marked as a duplicate of bug 154602 ***
