<div dir="ltr"><div dir="ltr">Thanks Philippe, Sorry for the late follow up. I got side tracked. What's the best way to build and play with wpe in an uninstalled env? I use gst-build but when I try to buid wpewebkit it needs gstreamer. When I try to build wpewebkit inside gst-build env it fails.

Is this with git master? Note that the support for software rendering in wpesrc is available only in git master and that requires a development version of WPEBackend-FDO (1.7.x). Also what's the point of forcing swrast in Mesa in that pipeline? Setting LIBGL_ALWAYS_SOFTWARE=true might have side-effects in gst-gl :) Can you try a simpler pipeline with a non-GL sink?
