--- Comment #34 from vincent <vljn at ovi.com> ---
FWIW I also tested with R600_DEBUG=nohyperz and R600_DEBUG=nodma but it doesnt
solve the issue (although I'm not sure these env var are useful on radeonsi).

Unfortunatly egltri_screen display a triangle but sometimes and in a very
broken way : always a message about gpu stall, sometimes it display garbage,
sometimes a triangle but on the right or on the left. The gpu is definitively
doing some rendering works correctly but it fails before swapping buffer.

BTW why eglinfo also make the gpu stall ? As far as I can tell there is no draw
operation involved, just egl initialisation and unintialisation.
