I got the same thing today.
I was playing Commander role; prior to that bug, I checked the map (it was still aligned correctly), only that my character froze, actually I couldn't close the map anymore, I had to type suicide.
Then, I couldn't use any radio (I used them moments before and I didn't change my key bindings), so I had to change class since I couldn't call in artillery etc.
Then, when I press M, the map shows up misaligned like this:

Changing class didn't fix it for me. I wouldn't know how to reproduce these bugs, nor if they are related.
