I've been experiencing the same issue as here

After some testing and asking around, the issue was fixed by installing microsoft's propietary font packages. I'm not sure exaclty which font package fixed the issue at this point. I did have several Monospaced fonts already installed, so I don't think that's the issue font.

No errors were shown in the console, regardless of the -debug flag.

I actually don't have enough information or knowledge of the IDE to debug it or I'd provide more exact information, I just figure someone should know.
