Thanks. The above attachment suggests to me that this is a virtual machine or something unusual, because:

[ 34.403367] tomasz gnome-shell[1410]: Failed to initialize accelerated iGPU/dGPU framebuffer sharing: Do not want to use software renderer (llvmpipe (LLVM 9.0, 256 bits)), falling back to CPU copy path
[ 34.918603] tomasz gnome-shell[1410]: glamor: 'wl_drm' not supported
[ 34.918603] tomasz gnome-shell[1410]: Missing Wayland requirements for glamor GBM backend
[ 34.918603] tomasz gnome-shell[1410]: Failed to initialize glamor, falling back to sw

So that's where all the CPU is going... It's Mesa trying to use all the CPU cores to emulate a GPU in software. Probably.

Next, please:

1. Run: lspci -k > lspcik.txt
   and attach the file 'lspcik.txt'

2. Run: glxinfo > glxinfo.txt
   and attach the file 'glxinfo.txt'

3. Tell us if you have any gnome-shell extensions installed.
