Hi, this has driven me nuts allready, picture included from worst kind of scenario.
these issues are constant, and happens everywhere in AS7 which makes writing code impossible.
System:
win10 64bit
R9 290 video card(have tried older drivers)
newest atmel installation.
i had these same issues with android studio, but that was sorted out with -> Enviroment variable : _JAVA_OPTIONS :-Dsun.java2d.d3d=false -Dsun.java2d.noddraw=true, maybe there is something similar for AS7??
