fedora: gnome-shell high cpu usage

installed fedora on a couple of newly acquired desktops and noticed slow graphics rendering. when i checked processes running gnome-shell was surprisingly eating up too much cpu. i have the same fedora setup on more than a handful of desktops but didn't experience this issue. tried reinstalling fedora and got the same slow graphics and high cpu usage.

read a lot of posts about this happening even on ubuntu boxes.

for now, i'm adopting others' solution of enabling Settings > Graphics > Forced Fallback Mode > ON

yes, this disables the dynamic graphics effect on the interface, but whatever works for now is always welcome until we find a better solution.

to note: setups with no graphics issue are using foxconn and dell boards. the two desktops with issues are using msi boards.

update: issues with msi boards solved by adding a video card! :)
