Ever since the last update, I occasionally get very weird fonts happening. They're not any actual letters, but they replace specific letters. For example, after playing with no issues for a while, I'll start experiencing this effect where, say, every J is replaced with a block of dots and weird lines. Slowly, all the letters will eventually get the same way during a play session. If I restart, it goes back to normal for a while, then it starts again. It happens to numbers too.
I haven't seen any other people mention this bug, so I thought I'd bring it up.
I am playing on a GForce GTX 460M.
Again, this only started since the last update and I've tried verifiying my files and reinstalling and it keeps happening.
