I’m using a VIM3 running the official CoreELEC 21.3 (Kernel 4.9).
I’ve noticed screen tearing/flickering whenever there is data writing to my NVMe SSD (I’ve tested Samsung, SK Hynix, and Kingston drives, and the issue persists on all of them).
The fix mentioned in this thread: Ubuntu Desktop 5.12 screen flickering issue with NVMe - #4 by numbqq works perfectly on CoreELEC 22 (Kernel 5.15), but it is ineffective on the stable CoreELEC 21 (Kernel 4.9).
Is there a specific solution or patch available for Kernel 4.9?
