--- Comment #9 from Yaroslav Halchenko debian@onerussian.com --- For me with DRI_PRIME=1 it even sometimes does not render at all... first I thought it happens only with external display, but nope -- also happens straight on laptop screen unpredictably. But no crashes from that so far during my trials
