Emacs 26.1 was pretty rock solid on macOS, using --with-ns. In 26.1.90, I notice semi-frequent redisplay problems that don't reproduce when I try the same command again. For example, sometimes when I enter Gnus, and everything looks fine, suddenly the majority of the screen will go black (except for the current summary line). Moving the cursor brings back the article I'm reading, but even C-l doesn't redraw the summary lines. I have to page down and page back up to get them to redraw again. This happens in all types of buffers: code, eshell, Gnus, Org, etc. The basic behaviors I've seen are that either the current line goes black, and everything else is fine, or the whole frame goes black. I'd never seen this behavior before 26.1.90. -- John Wiegley GPG fingerprint = 4710 CF98 AF9B 327B B80F http://newartisans.com 60E1 46C4 BD1A 7AC1 4BA2
