same and the solution atleast for me is to just go to the standard graphics settings and it goes back to normal. Just enter it, nothing else.
Incompatible with 0.36, but a quick search for "version" in the main .lua script (extreme_graphics/lua/ge/extensions/core/ckgraphics.lua) and adding 0.36 to the hardcoded whitelist fixes that. I've not encountered any issues after a quick test
