Corrupted mouse pointer icon in Mir/Unity8

[dinamic]

Ubuntu 17.04 unity8

corrupted mouse pointer icon (see attaches screenshot, the mouse pointer is hovering places/Home on the file manager app, the orange block/square)
mostly i see when i run apps with Xmir, maybe stuff that uses SDL, mpv, neverball

and it's only the arrow pointer, the rest are not affected, resize arrows etc

side effects, some strings corruption is some apps (note: i can't reliably reproduce this bug, but i see it happen occasionally when running apps with Xmir, video players, games)

see attached screenshot

It looks like a corrupt texture cache/atlas in Unity8 itself...

Status changed to 'Confirmed' because the bug affects multiple users.

Do you use nvidia?

1684240 seems to be the same issue. In my case this can be reproduced under Kubuntu with Nvidia.

This bug is for Mir/Unity8. So if you have issues in Kubuntu or Unity7 please use a different bug.
