From: Jonathan Corbet <corbet <at> lwn.net> To: 76481 <at> debbugs.gnu.org Subject: bug#76481: 31.0.50; Extreme weirdness with GDK_SCALE= Date: Fri, 21 Feb 2025 15:11:26 -0700
With emacs built to use GTK, and running under Wayland... run: $ GDK_SCALE= emacs The result is a number of hallucinogenic effects ranging from emacs just showing up as a black square on the screen to window-resizing attempts setting the frame to random sizes unrelated to mouse movements. Things work much better without GDK_SCALE= and I can happily take that out (it was put into my scripts years ago for long-forgotten reasons), but other users may be tripped up by this too. This happens even with "emacs -q".
