[Anything else here]
Maybe it's a bit early to report bugs related to radv. Things are certainly improving a lot: it used to crash my whole system. I can now go in-game. Simple games seem perfect (dragon's lair for ex). Others are rather good (mario super tennis), but with some glitches.

I suppose this is more related to the radv driver, so I created a bug report here with a few fifo files

Trying today on mesa stable 17.1.2
Trying the "round vertex" option makes a big difference in behaviour.
With this option on: I have a black screen until the race track starts to display. Then I have a sharp picture and a little black square.
With this option off: I can always see the screen (=it's never black). On the tracks, I have a big square in top left corner.
Finally, I tried with the OGL backend."round vertex" has little influence, but I noticed a slight purple square in top left corner with "IgnoreFormatChange" On (same size as with vulkan, but less visible). It completely disappears, with "IgnoreFormatChange" Off.
Hope this gives the dev some clues.
