alacritty: Crash at large window size in X

OS: Arch Linux running in latest VirtualBox Alacritty Version: 0.4.1

I’m running alacritty without 3D acceleration because the VirtualBox driver doesn’t support OpenGL 3.3:

LIBGL_ALWAYS_SOFTWARE=1 alacritty

The only output I have is this:

X connection to :0.0 broken (explicit kill or server shutdown)

This only happens at a very high resolution (which I added myself):

xrandr --newmode 3840x2160 712.75 3840 4160 4576 5312 2160 2163 2168 2237 -hsync +vsync
xrandr --addmode Virtual1 3840x2160
xrandr --output Virtual1 --mode 3840x2160 # this one breaks it
xrandr --output Virtual1 --mode 2560x1600 # this one works

Note also that kitty works normally when I run it the exact same way, in any of the resolutions.

Similar issues:

https://github.com/alacritty/alacritty/issues/3007 (same error)
https://github.com/alacritty/alacritty/issues/3214 (also a problem with high resolutions)

Output using -vvv

swrast_dri transfers images inline via xcb_put_image. By default, modern X servers allow a maximum message size of 16MB which is not enough to transfer large images. Start the X server with -maxbigreqsize 127 to increase the limit to 512MB. This is the maximum possible and is enough to support 10000x10000 window sizes.

If you use startx, use startx -- -maxbigreqsize 127. Otherwise consult the manual of your display manager.

Of course this will use a very large amount of memory.

startx – -maxbigreqsize 127

@mahkoh How would I configure this setting when I do not start X11 manually? I use systemd, sddm and i3.

same setup here. You have to edit /etc/sddm.conf and change from

# Arguments passed to the X server invocation
ServerArguments=-nolisten tcp

# Arguments passed to the X server invocation
ServerArguments=-nolisten tcp -maxbigreqsize 127

Worked for me.

I went ahead and tried upgrading my kernel from 4.14 to 5.15 and that seemed to fix the resizing issue for me. inxi shows an updated render now.

Does it show anything in --print-events -vvv, it should show at least something in them?

Note, I’m not interested in using any virtual box(only qemu is allowed), sorry.
