I also see a lot of these messages in The Talos Principle on a R9 270X here:

It looks like the game is stuttering when new textures are loaded or something
like that. For example I go to a new area and when I walk straight, everything
is smooth. When I start looking around, I get stuttering. This happens only
once. After the initial stuttering, the game runs at normal speed again.
I also see some graphics corruptions like in
https://bugs.freedesktop.org/show_bug.cgi?id=88978 which I can also see in dota
itself.

I'm running mesa 5750595ca97b2f8f18d22af35b431a6c66dd899a and llvm r231783.
