<pre>Patch didn't help. Actually it initially didn't compile for me
(AMDGPUWindowExposures_oneshot was undefined) but I added a prototype for it.
Indeed DRI3 didn't seem to affect it on further tries (not sure what happened
originally).
But when I comment out the "Virtual 4096 4096" line it consistently works, and
if then uncomment it it crashes.
To clarify the crash is because pScreen->root is 0. It doesn't crash without
rotation because that's not queried in the else case (I verified that it was
also 0 without screen rotation).
And I'm guessing it's not 0 when the Virtual setting isn't used.
Alternatively the code never reaches that point, I can try to verify that or
anything else you want. Though hopefully you'll be able to repro it now?</pre>
