BT from gdb for the WebProcess I'm using epiphany 3.27.90-38-gdb76a7f with WebKitGtk+ 2.19.92 from gnome-nightly's flatpak. I see often crashed tabs. When inspecting in my system with coredumpctl I've found several cores. In this case, the WebProcess is SIGSEVing. I do not know the conditions for this.

This is the same as
https://bugs.webkit.org/show_bug.cgi?id=182760
I gave it a look, but despite I know why it crashes, I haven't found how we are reaching the crashing situation. But this bt is more complete, maybe I can get more info from it.

A comment that may help: "just 1 quick comment regarding what I saw in the CoordinatedGraphicsScene.cpp::purgeGLResources code, the for loop calling the proxy->invalidate destroys the platformLayer which hold the unique pointer to the glContext and that happens just before we destroy de texturemapper which needs this context" This could mean that the destruction of the proxies is somehow changing the current context in the compositing thread, and it's not putting back the appropriate one (the one created by the ThreadedCompositor). As the replaced one is destroyed, there's no current one when destroying the TextureMapperGL.

: """I believe the crash is due to the clicking on the basket in the top right while the basket's contents popup is still being faded in at:

1. Open Epiphany 2. Browse various webapps (e.g.; tuleap.org, ring.cx) 3. Observe for failed loads, errors
