--- Comment #70 from [email protected] --- I'm also a Linux user, and have had slow scrolling issues for large documents off and on for a while. Before, on X11, it would happen that scrolling with the mouse wheel or by dragging the scroll-bar would be unbearably slow, but using the page-up/page-down keys would still be quick. I haven't found the zoom percentage to make any difference; however, at one point (a couple of years ago) I was able to circumvent the slowness by enabling the option "Tools > Automatic Spell Checking". That was a weird one (why would enabling a check cause a speed-up?). However, for the past several months, I have been using Wayland and Qt6. Currently, LibreOffice says its using "VCL: kf6 (cairo+wayland)". And just recently--within the last four updates--all scrolling, whether by mouse, scroll-bar or page up/down keys is so slow in large documents (>40 pages, it gets slower the more pages there are) that the program is practically unusable. System resources definitely aren't the issue, as I have an 11th gen i7, an RTX 3080 and 32GB of ram. When performing many scroll actions (the document won't actually perform them, but just locks up), my fans will spin up a bit and the CPU usage will go up 4-8%. I wouldn't say the RAM usage is affected (no noticeable change). -- You are receiving this mail because: You are the assignee for the bug.
