Update: I got Cinnamon working perfectly again with these tweaks. The 2-3 second micro-stutters are completely gone, even with Antigravity IDE open, YouTube/Spotify playing, or heavy multitasking. I did a few things:
1. Disabled the "Transparent Panels" extension (it was adding unnecessary GPU load). 2. Enabled triple buffering for Clutter (Cinnamon's rendering backend): echo "export CLUTTER_PAINT=triple-buffer" | sudo tee -a /etc/environment. 3. Added the Oibaf graphics drivers PPA for the latest bleeding-edge Mesa: sudo add-apt-repository ppa:oibaf/graphics-driverssudo apt update && sudo apt upgrade. I don't know which one actually fixed it, but clearly one of them fixed the problem I was having with Cinnamon. And now everything is back to normal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2137080 Title: Periodic micro-stutter every 2-3 seconds in Cinnamon on AMD Renoir (Ryzen 3 4300U + Vega 6) with kernel 6.14 series To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2137080/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
