Description Cédric Bellegarde 2019-09-05 05:01:57 PDT 
version: webkit2gtk3-2.25.92-2.fc31.x86_64

What is happening? A blank page in Web view and this message "Cannot create EGL window surface: EGL_BAD_ALLOC"

Happens in all application with HW acceleration on (Devhelp for example).
Comment 1 Cédric Bellegarde 2019-09-14 14:51:28 PDT 
Does not happen on ArchLinux so looks like a Fedora 31 only issue.
Comment 2 Guilaume Ayoub 2019-09-16 10:00:13 PDT 
This bug also happens on my Gentoo system using Epiphany, when using HW acceleration. It's not a Fedora-only issue.
Comment 3 Cédric Bellegarde 2019-09-16 10:13:10 PDT 
Ok, so reopening...
Comment 4 Guilaume Ayoub 2019-09-16 12:42:15 PDT 
The bug happens with Mesa 19.2.0-rc2, but not with 19.1.6. That's why it happens on Fedora and Gentoo, not on ArchLinux.
Comment 5 Carlos Garcia Campos 2019-09-17 02:45:54 PDT 
Ok, this is because mesa now fails if eglCreateWindowSurface() is called twice for the same window/pixman. And WebKit is doing that when not using the wpe renderer due to a bug.
