Re: Fun with buggy video card drivers

It bites other applications as well - the Enlightenment window manager would trip over it *all* the time (as in *every time* you enter/left a window - the cursor was almost NEVER right). Particularly interesting things happened if you happened to be moving the cursor fast enough that one mouse position update was "outside" the window, the next was "inside", and it never hit the window decoration pixels - it was possible to end up with some random cursor in reverse video. The problem seems to be a bad interaction between the new Xcursor code with the support for animated cursors, etc and the nv driver. It may be a generic problem with drivers that use software cursors, and work OK for hardware cursors, or something like that, I've not investigated.
