I saw this problem 1/4 times I let the VM's screen go black by leaving it idle.
The problem might involve a race condition. The gpu pointer in
KWin::DrmGpu::pageFlipHandler might've been corrupted or freed due to the
pageflip timeouts then used in KWin::DrmGpu::presentationClock. Should I report
this problem to Kernel Bugzilla or some other kernel mailing list? Thanks.
