Bug 239429 – [GTK][Wayland] Evolution crashes when closing the message compose window (crash in webkitWebViewBaseMakeGLContextCurrent)

• Component: WebKitGTK
• Status: NEW

[Jennifer Graul]

Using NixOS unstable (22.05pre369524.5181d5945ed), webkitgtk 2.36.0 and the Sway window manager, Evolution 3.44.0 crashes with a segmentation fault when I try to close the message compose window.

According to [0] this looks like the bug [1] which should already be fixed.

Here is the backtrace of the segmentation fault:

I agree, looks identical...

[Carlos Garcia Campos]

I'll check this issue, but I think evolution composer web view should just change the accelerated compositing setting policy to never or ondemand.

Do you mean as a workaround for the time being?

There used to be set the WEBKIT_DISABLE_COMPOSITING_MODE, but it had been removed long ago (see [1]). I can return it back, though I think the environment variable has a different name these days, no?

[1] https://gitlab.gnome.org/GNOME/evolution/-/commit/12453d8744fc1a4f6

[Carlos Garcia Campos]

I mean in general, I guess the compositor view doesn't really need hardware acceleration. But do not use any env var, we have a setting for that, just set the policy to never or ondemand only of the compositor web view.

[Milan Crha]

Can people still enable acceleration when the option is off in the settings? That was the main intention for the env variable usage. Note that had been removed from evo due to issues with typing, as the commit I referenced suggests.

I did that for 3.44.1+ with:

[SyntevoAlex]

Many Eclipse users are having this crash:
https://github.com/eclipse-platform/eclipse.platform.swt/issues/179

[Gietki]

Hi, as SyntevoAlex pointed out this is really a blocker for all Eclipse users. May we ask you to fix the issue in the library and release it soon? Cheers!

[Michael Catanzaro]

This looks very similar to bug #201507, which has been open for three years. Nobody knows how to fix it. We don't even know whether it is a WebKit bug or an OpenGL driver bug. I would not expect any quick fixes here.

If you need it solved urgently, I would do what Evolution did and just disable hardware acceleration entirely. But be aware that might stop working in the future....
