Hello. I recently switched back to Arch Linux (64-bit) and I'm running with the catalyst-hook package from Vi0L0's inofficial repository. When I play games, or also when I'm using hardware acceleration in VLC, these artifacts appear on the screen. They disappear quickly if you update the screen, so they are not so prevalent on the actual gaming screen. They however flood my second screen. In case of VLC they are just constantly blinking all over the place. I've googled the issue, but couldn't find anything that helped. If I alt-tab out of the game all artifacts disappear, but then reapper later after I've continued playing for a few minutes. This is very annoying.

Is there anything that can fix this? Please help!
