Ah, interesting, thanks!

The bisecting finished showing 2.99.917-4-g986cb23 (Jan 6) "sna: Enable
mmap(wc) support by default", as the cause for the issue. 

Additionally with the commit appeared graphics corruption, which persisted thru
2.99.917-17-ge53087e, but it was not present with 2.99.917-35-g6a6efd3 or
after.
