Does anyone know when an update may be fixing this issue? Having to disable LVDS (GRUB_CMDLINE_LINUX="video=LVDS-1:d") to get descent performance from an external VGA display is not ideal, as I would call it a temporary fix, as when one wants to use the internal LVDS, it has to be reenabled each time and a restart performed.
Turning off the LVDS using only VGA in "system settings/displays", did not make any difference to the slow GPU performance unless I booted up with VGA unplugged or use external VGA with LVDS disabled in GRUB
