Quick typing makes the cursor disappear and reappear erratically. Restoring the window margins to their original value of 0 makes it go away again. To reproduce this in a minimal Emacs session, I've used the following in the scratch buffer: (blink-cursor-mode -1) (set-window-margins nil 0 (- (window-width) 50)) Then one can hold down a key and watch the cursor carefully as it starts flickering until you let go of it. Is anyone else able to reproduce this? What would be suitable debugging steps to find out the reason behind this glitch? Could it be the fault of my graphics setup?
