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)
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.
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.
