webgl not working on raspberrypi3 with ANGLE

[guijemont]

Describe the bug

When compiling the wpewebkit with recent upstream WebKit, the ANGLE backend for webgl (or webgl2) is not working on raspberry pi 3, on kirkstone. Since 254947@main ANGLE is the only way to have webgl in WebKit.

When running XDG_RUNTIME_DIR=/tmp cog -P drm http://get.webgl.org/ with the generated image, the spinning cube does not appear. The output of cog is the following:

(cog:615): Cog-DRM-WARNING **: 13:35:15.961: Renderer 'modeset' does not support rotation 0 (0 degrees).

(cog:615): GLib-GIO-WARNING **: 13:35:16.089: Your application does not implement g_application_activate() and has no handlers connected to the 'activate' signal.  It should do one of these.

This also seems to reproduce with older revisions since ANGLE was made the default, unless compiling with -DUSE_ANGLE_WEBGL=OFF, which is done in the attached local.conf.

To Reproduce

Files to reproduce the behavior:

1. local.conf
2. bblayers.conf
3. hash references of each repository of each used layer:
   • poky: 453be4d258f71855205f45599eea04589eb4a369
   • meta-openembedded: 0b78362654262145415df8211052442823b9ec9b
   • meta-raspberrypi: dacad9302a92b0b7edf8546cdcad1f8ef753e462
   • meta-webkit: 3b2f69f7cb057eaf9091afb21153533bcfcc8251
4. local changes applied in the build environment
   • devtool modify -n wpewebkit /path/to/webkit/source to easily test different revisions
5. bitbake command causing the error
6. • bitbake core-image-base or bitbake wpewebkit
7. Error output

See cog error output in bug description.

Expected behavior

Spinning wireframe cube when rendering http://get.webgl.org/.

Screenshots

This is what http://get.webgl.org/ looks like when the bug happens:

Environment (please complete the following information):

• yocto release: kirkstone
• hardware targe: rpi3 32 bits

Additional context

I only tested with drm, don't know if it works under wayland.

In principle it was working fine in Wayland for a long time (at least ~6 months), next time that I fire it up I'll try to see if this happens with DRM.

I believe this was fixed in WebKit by r258932. Sorry I forgot to update this issue.
