Git commit c79ef9055f3b6717d0660998c1997dac9199eabb by Xaver Hugl.

Pushed by zamundaaa into branch 'master'.
backends/drm: asynchronously wait for idle before doing modesets
The previous code relied on waitIdle() *always* working, which isn't the case.
Sometimes,
weird kernel bugs can make the timeout trigger wrongly, and sometimes, the
kernel just
doesn't send a pageflip event in a reasonable time frame or at all.
This should fix at least most cases from
