Your system information

• Steam client version (build number or date): Feb 18 2019
• Distribution (e.g. Ubuntu): Gentoo (Kernel 4.19.28, Mesa 18.3.4)
• Opted into Steam client beta?: No
• Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

When attempting to start Goldsrc games such as Counter-strike 1.6 or Counter-strike CZ, the game doesn't open up, but it is still running, the word "Running" appears next to title name on Steam library, and I can see hl.sh and hl_linux when running "ps -A | grep hl", and I can only close it by using "kill -9" command, even exiting Steam doesn't close it.

Tried reinstalling Steam, CS, etc... Not working

Source games such as CSGO and CSS work flawlessly.

BTW I am using Steam runtime libraries.

P.S. When I had an Nvidia GPU with Nvidia proprietary drivers, the games used to work.

Steps for reproducing this issue:

1. Get an AMD GPU which supports AMDGPU kernel driver.
2. Use AMDGPU kernel driver with Mesa (Not proprietary driver).
3. Attempt to start any Goldsrc game.
