We did have a problem when closing the game and music was playing which caused a crash. This has since been fixed. Could it be this issue you’ve come across?
I think we’re releasing a hotfix today for this crash: Font crashes engine with OpenGL error - #10 by Mathias_Westerdahl
There shouldn’t be any change to how fonts are rendered, but the hotfix and crash might be related to what you are experiencing with fonts. @jhonny.goransson?
