Hello,
I got the following error when doing ediff-files3 on three random
files (the full backtrace is in attachment backtrace.txt):
Debugger entered--Lisp error: (wrong-type-argument window-live-p nil)
I could reproduce the bug in the following way:
- launch emacs -q -Q
- (setopt ediff-window-setup-function 'ediff-setup-windows-plain)
- increase font size quite a bit with global-text-scale-adjust
- call ediff-files3 on three random files
- the ediff control panel doesn't show and I get the error shown above
I could make the bug go away by either:
- decreasing font size with global-text-scale-adjust
- set ediff-split-window-function to 'split-window-vertically
This is the output of wlr-randr:
eDP-1 "BOE 0x0764 (eDP-1)"
Make: BOE
Model: 0x0764
Physical size: 310x170 mm
Enabled: yes
Modes:
1920x1080 px, 60.012001 Hz (preferred, current)
Position: 0,0
Transform: normal
Scale: 1.500000
Adaptive Sync: disabled
And this is a font setting I could reproduce the bug with:
(custom-set-faces
'(default ((t (:family "DejaVu Sans Mono" :foundry "PfEd" :slant
normal :weight regular :height 132 :width normal)))))
Thank you
Andrea
