This may actually be in the WM, or cause by it. When I was looking for a new WM for users, I did note this behavior on some and not others. Since I was running on the same kernel and video driver, it seems to me that either the WM is actually doing this in areas where it doesn't show the pointer, or that it is loading an X driver with is causing this. Since I did see this first in a VM, then on a live fc16 install, using totally different video hardware, it's unlikely to be just poorly supported hardware.On Thu, 21 Jun 2012 20:45:15 +0100 Ian Malone <ibmalone@xxxxxxxxx> wrote:Hi, has anyone else seen this? Since installing F17 (probably the first clean fedora install I've done since single digits), I get a flickering mouse pointer when the system is busy. This might be related to the fact the mouse pointer hides instantly (no pause) when stopped over certain window areas (list items seem most common). Asking partly because I'm not sure what component to report this as a bug in.One cause of that can be mishandling of memory bandwidth and FIFO settings in the graphics card. My first guess therefore would be to file it against whichever X server you are using and include the X trace, an dmesg including a boot with drm.debug=7, an lspci and an lspci -vvxxx (as root)
The OP might try using VNC for access, to see if that provides any useful info. I do believe the WM is making the cursor vanish when not moving.
