Subject: | bug#34127: 26.1.91; Redisplay issues with tramp |
Date: | Fri, 18 Jan 2019 17:02:04 -0500 |
I've been noticing various display anomalies when using the latest Emacs 26.1.91 pretest. Some cases are hard to capture or categorize, but it seems like I'm seeing more "flashing" for redisplay than I usually do. The case I was able to capture was when using tramp. If I create a new tramp connection (after calling M-x tramp-cleanup-all-connections), I see a strangely blank screen from after calling the command (say C-x C-f "/-:slc:") until the directory gets displayed. Please see the attached picture. That blank screen behavior is new. In 26.1, the frame contents continue to be displayed while the command is running. - Tim In GNU Emacs 26.1.91 (build 1, x86_64-apple-darwin14.5.0, NS appkit-1348.17 Version 10.10.5 (Build 14F2511)) of 2019-01-07 built on builder10-10.porkrind.org Windowing system distributor 'Apple', version 10.3.1561 Recent messages: Tramp: Sending command ‘exec ssh -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none slc’ Tramp: Waiting for prompts from remote shell...done Tramp: Found remote shell prompt on ‘slc’ Tramp: Opening connection for slc using scp...done Directory has changed on disk; type g to update Dired Tramp: Opening connection for slc using scp...
