Unity works very fast but pretty unstable on my PC (with Intel GMA X4500HD video card). For example the Ubuntu purple-black splash screen is stuck as the desktop background (changing it in the settings changes nothing) and occasional UI hangs (while switching to a console with Ctrl+Alt+# still works) are frequent.
I would gladly sacrifice fancy GPU-accelerated effects if possible. Are there such tweaks available?
Please don't suggest using another DE - I know of them but would like Unity if possible.
