Cursor corruption

I'm seeing spontaneous cursor corruption for about 2 months from now. It rarely
happens in a usual workflow, but it almost always happens when I use VM in qemu
or virtualbox.

I'm running Fedora 25 4.11.12-200.fc25.x86_64, xorg-x11-drv-intel.x86_64
2.99.917-26.20160929.fc25

No errors in dmesg, no errors in /sys/class/drm/card0/error. Switching VTs or
screen resolution doesn't help, the cursor is still corrupted.

Sometimes the fonts in GTK3+ applications became corrupted with mouse
corruption, but that happen rarely.

I'm using Fedora's defaults: DRI2 and SNA.
