X-Widget: assertion '!widget->priv->alloc_needed' failed

A6GibKm commented 3 years ago

When opening a file using xwdiget I get an error

(emacs:150587): Gtk-CRITICAL **: 12:12:04.741: gtk_widget_draw: assertion '!widget->priv->alloc_needed' failed

(emacs:150587): Gtk-CRITICAL **: 12:12:21.983: gtk_widget_draw: assertion '!widget->priv->alloc_needed' failed

This seems to be harmless.

How to reproduce: Not really see below

As in #69, create a file with contents

             I can run x11 applications now. Rest usage of toolbox
             looks fine.

             After commenting out `default_sysctls = ...` from
             /usr/share/containers/containers.conf I was able to
             test and verify that this update works. I was pointed
             out to
             https://github.com/containers/podman/issues/7766  I am
             able to run x11 applications again! Ctrl + P also
             works as expected. /media is present, same for udev
             database.

In ~/some.html

Then run inside emacs

(xwidget-webkit-browse-url "file://home/USERNAME/some.html") or whatever is the complete path of the file.

I cannot reproduce this one, but I do see #72

A6GibKm commented 3 years ago

This is indeed not reproducible with emacs -Q. I will try too look a bit deeper into it.

It is probably due to my personal config + Doom Emacs, since it is not reproducible with Doom emacs without my personal config either.

A6GibKm commented 3 years ago

Update: I found a way.

Steps to reproduce

Enter emacs -Q
Run (xwidget-webkit-browse-url "file://home/USERNAME/some.html")
Press C-x C-b to pop up the buffer selection
click on the xwidget buffer

Relevant Note

This is somewhat reproducible in master, but slightly different. In master I see the error four times instead of two, this suggest that the issue might lie in the master branch. I will file a bug later with CC to @fejfighter.

fejfighter commented 3 years ago

yup Confirmed with new recipe

Both this issue and #72 were reported at http://debbugs.gnu.org/cgi/bugreport.cgi?bug=44034.
