bug: gnome 44, alacritty, wayland => crash

Open crepererum opened this issue 2 years ago • 7 comments

Description

I don't know exactly where to file this bug, so I'm filing it here for visibility but we may wanna link Mutter/Gnome and Alacritty issues here.

When forge is enabled, I'm having trouble starting Alacritty. It fails with:

Buffer size (10x685) must be an integer multiple of the buffer_scale (2).

Starting Alacritty w/o forge works.

Problem Explanation

Some googling shows that this seems to be a common Wayland issue, but I'm not entirely sure if the compositor (=Mutter) or the client (=Alacritty) is too blame. Fact is that forge seems to trigger this issue.

Expected Behavior

Alacritty just works.

Reprodution

Steps To Reproduce

Steps to reproduce, if applicable:

  1. Get Gnome 44.1 and alacritty 0.12.0 and forge 68
  2. Start alacritty

Monitor information

See above, no X, it's Wayland.

The problem also does NOT occur under gnome 42, it just appeared after the upgrade to version 44.

crepererum avatar May 17 '23 18:05 crepererum

Hi @crepererum, to confirm, Alacritty crashes in Wayland and not Gnome 44? Also, did you try to restart gnome-shell? This happens to me sometimes on Blackbox flatpak but usually after updating the app. Restarting the OS fixes it.

jmmaranan avatar May 17 '23 21:05 jmmaranan

I ran Alacritty 0.12.0 in GNOME 44.0 but not GNOME 44.1 - it is working and not crashing. I am using Boxes though to test (slight flicker in that VM).

to confirm, Alacritty crashes in Wayland and not Gnome 44?

I don't understand that question. Alacritty crashes, when Gnome 44 runs in "Wayland" mode (not the old-style X11 mode). But Gnome 44 / Wayland itself (i.e. the display server and shell) don't crash.

Also, did you try to restart gnome-shell? This happens to me sometimes on Blackbox flatpak but usually after updating the app. Restarting the OS fixes it.

It's pretty much independent of restarts / updates. Also I used a non-sandboxed version of Alacritty (i.e. no flatpak involved).

I ran Alacritty 0.12.0 in GNOME 44.0 but not GNOME 44.1 - it is working and not crashing. I am using Boxes though to test (slight flicker in that VM).

Can you try to set the Gnome display scale to 200%? (Settings > Display > select your monitor > scale: 200%).

crepererum avatar May 22 '23 08:05 crepererum

Was asking if Gnome or the Alacritty crashes. I will try to see if display scale 200% reproduces it

jmmaranan avatar May 23 '23 21:05 jmmaranan

OK, so the assertion might be part of mutter actually, but the effect is that Alacritty gets killed. This is new in Gnome 44 probably due to https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2815

I'm somewhat surprised that an extension can trigger that. Maybe the positioning code in forge should round the window sizes based on the display scale?

crepererum avatar Jun 15 '23 09:06 crepererum

I had a similar issue recently where alacritty crashes with a similar error message. I did not trace the issue back to forge and I fixed it by building and running alacritty from the master branch. This might help: https://github.com/alacritty/alacritty/issues/7241
