Look what problem I have Screenshot - 756ee93496b83e9a12cfaec125ced1c3 - Gyazo .I did nothing, just downloaded and installed. Version 4.6.3
Try reinstalling it if that doesn’t work maybe look into your GPU drivers + if your using integrated graphics sometimes that causes issues.
if you reinstall it and there is problems then post some system specs and maybe a dev might have some input on the situation.
