--- Comment #29 from Eric Culp eculperic@gmail.com --- I'm pretty sure this is a duplicate of 38791. I added logging to the clipping functions in server/queue.c and it is indeed attempting to clip on a rect where top==bottom and left==right. If I apply that patch, it fixes the issue completely (at least for Darkfall Rise of Agon, which is the game I was reproducing with).
