List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: emacs-devel-bounces+ged-emacs-devel=m.gmane.org@gnu.org Original-Sender: "Emacs-devel" Xref: news.gmane.org gmane.emacs.devel:217970 Archived-At: I would like to insert a GLYPH_DEBUG message into xdisp.c to let me know that "UNKNOWN" triggered a redisplay when there is no command and/or timer function at issue. Step 1: On OSX (and maybe other Emacs OS builds), start GUI version of master branch built with Glyph Debug support. Step 2: Turn off blink-cursor-mode. Step 3: Remove the jit-lock timer function with (setq timer-idle-list nil) Step 4: Check the timer-list and timer-idle-list to ensure they are nil. Step 5: M-x trace-redisplay Step 6: Wait 1 to 2 minutes and watch how a redisplay is triggered with nothing more helpful than a singular `redisplay_internal 0` message. I would also like to please understand what this "UNKNOWN" event is and where it comes from. Thanks, Keith
