Quick follow up. I installed Ubuntu 22.04 on same RaspberryPI, and I noticed a huge performance difference with fractional scaling on Wayland. On Wayland I was unable to find any lag or delay or performance hit. On Xorg though, even Ubuntu 22.04 had the same performance issues as Ubuntu Budgie 22.04.
Thanks a lot for your expertise, Daniel. Much appreciated. We will make a note on our readme for Ubuntu Budgie ARM. I hope this helps someone down the line. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1974471 Title: mouse becomes laggy when fractional scaling is enabled Status in mutter package in Ubuntu: Won't Fix Bug description: Distribution: Ubuntu Budgie 22.04 LTS Kernel: 5.15.0-1007-raspi Package: libmutter-10-0 Architecture: arm64 Version: 42.0-3ubuntu2 5.15.0-1007-raspi On Ubuntu Budgie 22.04 LTS raspberry PI, turning on fractional scaling causes an issue where mouse movement becomes laggy and hard to control. This persists even if a reboot is performed after changing scaling settings. This was tested on Raspberry PI 4 8GB with 3 different mice. 2 USB wired, and one wireless with USB dongle. Same results with 3 mice. Disabling fractional scaling immediately solved the problem. Same tests were performed on Ubuntu Budgie 22.04 on amd64 laptop, with Intel CPU and Nvidia+Intel GPU. There was no issue with mouse performance on amd64 laptop.
