A square of garbage (made of old drawings of the screen) is drawn around the mouse pointer if the client software tries to use setpointer (I think).
Reproducible if two radeon cards (RS780 and RV770) are used at the same time to extend the desktop and there's a compositing window manager being used (KDE and GNOME have the problem, OpenBox does not).
So far I could see the problem with:
- Firefox when showing a big image (like this one: http://upload.wikimedia.org/wikipedia/commons/3/36/Axis_axis_%28Nagarhole%2C_2010%29.jpg which requires the mouse pointer to be changed to a zoom-in/out magnifier icon)
- VirtualBox when using Guest Additions (seamless pointer integration)
- rdesktop-vrdp always
I'm using xorg-x11-server-Xorg 1.14.4-9.fc20, with kernels 3.14-3.16 (already tried all three), and xorg-x11-drv-ati 7.2.0 (3.20131101git3b38701a.fc20).
Will attach a photo of the glitch.
