** Description changed: On Linux Mint 22.2 Zara (based on Ubuntu 24.04 Noble) with Cinnamon desktop, I experience periodic micro-stutters every 2-3 seconds. This makes the UI feel choppy: jerky scrolling, uneven loading icons in Nemo/browser, slight typing delays, and minor stuttering in YouTube/VLC videos (worse during screen interactions or refreshes). Hardware: Lenovo IdeaPad 3 14ARE05, AMD Ryzen 3 4300U with Radeon Vega 6 (Renoir) iGPU, driver amdgpu. The issue appeared on kernel series 6.14 (e.g., 6.14.0-37-generic) even after trying Kisak Mesa PPA upgrade. Downgrading to kernel 6.11.0-29-generic resolved it completely (smooth for hours of testing). Steps tried without success on 6.14: Removed all refreshing applets/desklets Disabled all window/desktop effects Restarted Cinnamon Monitored with htop/iotop (no obvious spikes) Upgraded Mesa via Kisak PPA - No issues on older kernel 6.11, suggesting a regression in amdgpu driver - or compositing (Muffin) in kernel 6.14 for Renoir iGPUs. + Update: + The issue persists in any kernel version, even in version 6.8.0-90. + + ================================================================================ System Info: System: -
