You can reproduct just use the steps in the screenshot. Just after I use qsub to create an interactive GPU window, then the problem happens. But the codex is good when i am in the login node.

What is the expected behavior?

Move the mouse / press Up/Down arrows / press Ctrl
The cursor starts flickering/jumping, and the screen output becomes garbled.
