Description network723 2017-11-25 13:42:50 UTC 
Source engine-based games, like Left4Dead 2, CS:Source, etc. freeze after window creation, consuming 100% of single cpu core. Running these games with R600_DEBUG=vs restores normal behavior.

TAHITI Pro, Mesa git master commit b6b4b2c6d825c056033c4111a67e83111b5f02e8

I tested R600_DEBUG=fs,vs,gs,ps,cs with Portal 2 and it did not help with RX560. However when Portal 2 hangs, core #9 (0-11) is used 100%.
Comment 3 network723 2017-11-25 16:26:21 UTC 
actually, it's not necessary R600_DEBUG=vs

R600_DEBUG=ps or R600_DEBUG=gs works too

Did you actually try the patch I linked you to? Because this still sounds an awful lot like bug 103902.

I don't know about original bug 103902 poster, but the proposed patch definitely fixes the issue for me.

Ok, so then let us keep this bug closed as a duplicate until differing information arises. And bug 103902 will be closed, once the patch lands on Mesa master.
