<pre>Hello!
I'm sorry. I'm reporting a bug which is currently not official released for the
3.22-branch. Archlinux is using currently a commit above 3.22.1, maybe to get
as many bugfixes as possible:
<a href="https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=ffb1ac56a8ae8b0261b9007115faed6206d4b06b">https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=ffb1ac56a8ae8b0261b9007115faed6206d4b06b</a>
Applications which use GLSL (WebKit2Gtk?) are broken and render a complete
black window on Wayland, including Window borders. Affected are at least
Epiphany and Evolution. This is the output from journalctl -rb:
Oct 23 21:37:42 cupcake evolution[1917]: Compile failure in vertex shader:
0:1(10): error: GLSL 1.50 is not supported. Supported versions are: 1.10, 1.20,
1.30, 1.00 ES, and 3.00 ES
My hardware is a ThinkPad X220 (SandyBridge, HD3000):
$ glxinfo | grep -i opengl
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile
OpenGL core profile version string: 3.3 (Core Profile) Mesa 12.0.3
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 12.0.3
OpenGL shading language version string: 1.30

OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 12.0.3

If I'm allowed to make a guess, here are my candidates:
<a href="https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=803362bb5d376613d671eb84f1ca642259158e20">https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=803362bb5d376613d671eb84f1ca642259158e20</a>
<a href="https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=d40c6f180fc832d6917a69b7a05080e402dc927e">https://git.gnome.org/browse/gtk+/commit/?h=gtk-3-22&id=d40c6f180fc832d6917a69b7a05080e402dc927e</a>
Likely you would notice this issue anyway before the release of 3.22.2, but I
think it better to report this as soon as possible.
Thank You</pre>
