I am running ubuntu 14.04 OS on a system76 serval laptop. I have the Nvidia driver installed, but it seams that sometimes some popup windows are not rendered properly in phpstorm. Any ideas how to fix this? Do I need to install a special driver?
Make sure your running Oracle JDK instead of OpenJDK or integrated-JDK (the one PHPstorm comes up with).
You can follow this guide about how to fix font anti-aliasing, but it could help with your Orace JDK settings.
