ungoogled-chromium crashes several times a day recently

UPDATE 1

~/.config/chromium-flags.conf

--force-device-scale-factor=2

The config file is there when I'm using xorg,
I'll delete it and see if it solves the problem.

Re: ungoogled-chromium crashes several times a day recently

what is the output you get when running the program from the terminal?

Not tested.

BTW after removing "~/.config/chromium-flags.conf", no crashes so far.
If it doesn't crash for 2 days, I can almost make sure that it's the flags that cause the problem.
Anyway the result will be here later.

Does it leave a somewhat usable coredump behind, https://wiki.archlinux.org/title/Core_d … _core_dump ?

Wrt the rest of the log, seems the buffer swap fails/stalls before glib aborts on what looks like an empty thread stack.

2. wayland or X11, xwayland?

Wrt the rest of the log, seems the buffer swap fails/stalls before glib aborts on what looks like an empty thread stack.
1. --disable-gpu

testing now, no crashes so far

2. wayland or X11, xwayland?

what is the output you get when running the program from the terminal?

When chromium exits, it shows an error as below

$ chromium

with ~/.config/chromium-flags.conf as below:

--disable-gpu-memory-buffer-video-frames

or

--disable-gpu

the console shows the same error when chromium exits

Re: ungoogled-chromium crashes several times a day recently

Crashes mostly inprivate symbols, occasioanlly showing QtCore??
But no strong pattern (recursions).

See whether it's actually an xwayland window (xeyes will tell) and in that case test "--ozone-platform=wayland"

It's an xwayland window...
Testing for wayland now.
