To confirm, deleting contents of
GPUCache directories solved that which was causing the issue for me. I was having issues with Zoom with menu’s not popping up, Chrome with delayed/stale renders and what seemed like freezing, and other electron or Chrome based app rendering issues.
If you want a quick way to discover any/all
GPUCache directories you may have in your home directory, try this:
find ~/ -name 'GPUCache' 2>/dev/null
2>/dev/null silences errors. This was important for me because I have rootless docker backed by BTRFS subvolumes and it spits out errors when “finding” through subvolumes. They are just benign/expected permission errors.
You can also use the command above on root, ie:
/, same command as above but remove the
~, which would scan your entire “storage” for any folder named
find / -name 'GPUCache' 2>/dev/null
