Should be ...requested-GTT+GTT-usage

I used to have similar issues with valley, but for my setup/card (R9270X) they
are fixed with current mesa + drm-next-3.19-wip.

One thing I always do is set CPUs to performance in case cpufreq messes things
up - may be worth a try to see if it helps.

What setting(s)/res do you run valley with?

It may be less hassle for you to use a phone, but FWIW the way I get
screenshots that include the HUD is to use xwd - for something fullscreen I
would before starting valley from a different xterm/console/whatever do
something like -

sleep 100 && xwd -root -out whatever.xwd 

then start valley and wait. To view "whatever.xwd" you can use xwud,to upload
you could convert to another "normal" format. You need some image program to do
this - I have ImageMagick installed and can just type in a terminal -

convert whatever.xwd whatever.png
