I can reproduce the redisplay issue, I never seen this before, maybe some recent change broke redisplaying. I tried to debug and in redisplay_internal, the value of garbaged_frame_retries has a very large number - about thousands order of magnitude. It never resets the 'garbaged' flag set in the selected frame. And I have no idea how to force the 'garbaged' flag to be reset. It infloops in these lines: /* On some platforms (at least MS-Windows), the scroll_run_hook called from scrolling_window called from update_frame could set the frame's garbaged flag, in which case we need to redisplay the frame. */ if (FRAME_GARBAGED_P (f)) goto retry_frame;
