Installed my Radeon RX 550 today. It's booting, glx gears gives me 500fps, but when i play Block' Hood i get black graphics everywhere.
Only the lake is blue. The game was fine on integrated intel hd 3000.
2D game runs fine, videos run fine.


blank_mode=0 glxgears:
ATTENTION: default value of option vblank_mode overridden by environment.
28974 frames in 5.0 seconds = 5794.684 FPS
28807 frames in 5.0 seconds = 5761.348 FPS


Here are some outputs:

glxinfo: https://pastebin.com/qxXYPeTL
dmesg: https://pastebin.com/fSEQBDHE
Xorg.0.log: https://pastebin.com/y7LQGfzB

Solved by emerging media-libs/libtxc_dxtn

This isn't some obligatory dependency for any package or driver?

I looked through your logs, I didn't notice anything wrong. But I think Polaris cards require radeonsi for OpenGL, and looking at the glxinfo, it seems like it's working.

EDIT: Oops, sorry, I posted after the solution was found.
