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.
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??
