--- Comment #25 from oirnoir <[email protected]> --- I can reproduce every part of this bug on my system as well. It's very annoying, hopefully it gets fixed soon. My system: DE: Plasma 6.1.4 OS: Fedora 40 x86_64 Kernel: Linux 6.9.12-200.fc40.x86_64 (I'm not on 6.10 due to a separate issue) WM: KWin (Wayland) CPU: Intel Core Ultra 7 155H (22) @ 4.80 GHz GPU: Intel Graphics @ 2.25 GHz [Integrated] LibreOffice: 24.2.5.2, kf6 I notice that when scrolling, one of my threads has very high usage while all others have very low usage. I experience considerable lag when scrolling through any Writer document. As in Comment 13, Running LO with QT_QPA_PLATFORM=xcb fixes the lag issues, although it messes with the application's display scaling. As in Comment 23, it appears to be a window size issue to me. I usually use 150% display scaling. Setting my display scaling to 100% makes the lag slightly better, but it is still very present. I have been able to get OpenCL working on my system, to test the theory of Comment 23. Sadly, this does not seem to affect the issue at all for me, as do any of the other graphical settings in LibreOffice itself. Smooth scrolling is disabled, as it makes the problem worse when enabled. I hope some of this information helps and look forward to any other contributions I can make to resolve this issue. -- You are receiving this mail because: You are the assignee for the bug.
