I'm using epiphany 3.29.3-63-ga1d6c75bf with WebKitGtk+ 2.21.5 from gnome-nightly's flatpak

When visiting https://asunnot.oikotie.fi/vuokrattavat-asunnot/helsinki/14691296 , the WebProcess SIGSEVs at WebCore::TextureMapperGC3DPlatformLayer::makeContextCurrent () at /run/build-runtime/WebKitGTK+/Source/WebCore/platform/graphics/texmap/TextureMapperGC3DPlatformLayer.cpp:61

I can reproduce 100%

I cannot reproduce the crash with current ToT in either case. The crash probably means that there's GraphicsContext3D doesn't have a glContext, despite it should have been created with the GraphicsContext3D.

Andrés, I think you were running some version of mesa, can you see if reproducing the crash with MESA_DEBUG=1 gives some extra info?

I can still reproduce with epiphany 3.29.91-1-g8f26b7ff3 with WebKitGtk+ 2.21.5 from gnome-nightly's flatpak.

Now, I have tried to launch from the command line and I see these errors:

$ flatpak run org.gnome.Epiphany
Cannot get default EGL display: EGL_BAD_PARAMETER
WaylandCompositor requires eglCreateImage and eglDestroyImage.
Nested Wayland compositor could not initialize EGL

Can this be somehow related to bug 178896 ?


May it be a flatpak problem?


I do not know how to proceed from here :(

Looks very similar to bug #201507.

Probably a duplicate, absent evidence otherwise....
