--- Comment #5 from [email protected] --- Hello, Wide screen means 3440x1440 in my case with a LG widescreen monitor. Please note that I have two monitors side by side (primary is 3440x1440 and secondary is 1920x1080). However I dont expect the presence/use of the second monitor to be related in any way to this bug because I did some testing by unplugging/removing it completely (both physically and in the nvidia driver/Xorg config) and saw no improvement whatsoever. https://bugs.documentfoundation.org/show_bug.cgi?id=90796 seems to be about High DPI which is NOT what I am talking about. I noticed that this issue is extremely bad when Libreoffice's window is maximized but improves when the window is manually resized to a smaller size. The smaller the window is, the more "fluid" the performance is and the smaller the Xorg CPU usage is.... Xserver is the culprit somehow... It is maxed out (at 100%) whenever I scroll in the documents or type or do anything that changes the physical layout of the document... Starting LO with the "SAL_USE_VCLPLUGIN=gen" switch makes things much much better (similar to LO version ca. 2016-2018). In retrospect I wonder if this issue is not the same (or at least caused by the same root cause) as the other bug report I opened last year: https://bugs.documentfoundation.org/show_bug.cgi?id=152657 There's clearly something bad going on between Libreoffice's graphical engine(s), Xorg (which is ANCIENT and obsolete?), and the Nvidia blob (that never was very efficient in Linux to begin with).. The exact same version of LO runs perfectly on Windows 10. -- You are receiving this mail because: You are the assignee for the bug.
