--- Comment #15 from M. Knepper <jake.m.knep...@gmail.com> --- Interesting. I'm really thinking it's resolution dependent. The higher your resolution, the more CPU scrolling consumes. I did record a video of this problem happening here. VIDEO OF BUG IN ACTION: https://www.youtube.com/watch?v=EXyMSzOVsds Keep an eye on the "CPU %" in HTOP. Some notes: It doesn't seem to matter if there are 200 pages or 50 pages. Linux kernel and AMD drivers (at least as of distros from the past several years) do not seem to make a difference. The issue exists on Xorg AND Wayland. The issue exists on Libreoffice 7.6+ as far as I've tested, and lastly, distro doesn't seem to matter. This doesn't seem to happen in other word processors. Word will only use 3% - 5% of my CPU when I'm scrolling, even with a document bigger than what's in LibreOffice. The issue is reproduceable on Windows 11 Pro, at least for me. Hardware: 13700k 7900xt 32gb DDR5 2tb SSD NVME Software/OS: Fedora 40 Linux 6.8x LibreOffice 24.2.3.2 hTOP Gnome 46 Gnome-Terminal GPU drivers, VCL version, GTK version, etc, etc - whatever is on Fedora 40 as of this video. Confirmed My Testing With: 2700x RX 580 8gb 16gb DDR4 1tb SSD SATA Linux 5.x LibreOffice 7.6+ Additional Notes: This seems to happen regardless of using gtk, qt, whether it's on Xorg, Wayland, a Debian distro, an Arch distro, etc. I've been able to confirm on different hardware and since version 7.6+ of LibreOffice. I tested it on 15k words to 50k words, 30 pages to 72 pages - it has high CPU usage either way. -- You are receiving this mail because: You are the assignee for the bug.
