My suggestions:
1. DebugWait / SwapbuffersWait: create the file
/usr/share/X11/xorg.conf.d/20-intel.conf with the following:
Section "Device"
Identifier "Intel"
Driver "intel"
Option "DebugWait" "true"
Option "SwapbuffersWait" "false"
EndSection
2. Add "i915.semaphores=1" to the kernel boot command line in
/etc/default/grub/ E.g.:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.semaphores=1" (then run
update-grub and reboot).
3. turn off font anti-aliasing,
4. set the DPI for your screen correctly,
^^Unfortunately multiple sub-systems manageo both of those. Suggestions welcome.
