--- Comment #14 from Chris Wilson <chris at chris-wilson.co.uk> ---
So I traced the error down to seemingly to the use of the source pixmap for
drawing the border. (Basically by modifying the drawing operations until I
found the exact path one of the window borders was taking, then tracing back
the pixmap to its creation.) On that path I spotted this:

    sna: Fix computing source bo for BLT operations

    If we migrate the pixmap to the GPU, use the GPU bo. This may fix an issue
    where we might end up using the CPU bo in a rare circumstance.

However, I never got the bug to reproduce reliably, so I am not sure if that
the complete fix.

Please test.
