Xorg log

Actually this is quite an old problem with my setup as well - ingame vsync
settings are ignored (always acts as on regardless of the setting) and I always
have to resort to vblank_mode override. i965, anv or radv don't have this
problem on the same setup so assigning to radeonsi.

Some maybe relevant settings:
window manager: xfwm4
compositing: off
no ~/.drirc file
TearFree: on
DRI: 3
mesa+llvm git (or older)

What's worse, this forced vsync occasionally goes out of sync with the display
refresh and I get stuttering (the game is surely fast enough, 100+ fps with
vblank_mode override). So if I run 60fps OpenGL game like Talos, it first runs
smoothly, after a while starts stuttering (for half a minute or so), then goes
back to smooth again and so on and on, while the fps counter shows "clean" 60.
