This beta to enable gpu acceleration on the Morph browser is working well for me, and enables it to run more smoothly, as well as use WebGL dependent websites.
In Terminal run:
sudo ubports-qa install xenial_-_gpu-browser
sudo -i
mount -o remount,rw /
cd /etc/profile.d/
cp disable-qtwebengine-gpu.sh disable-qtwebengine-gpu.old
rm disable-qtwebengine-gpu.sh
and then reboot
You can go to https://get.webgl.org/ to test whether Morph is supporting WebGL.
See https://github.com/ubports/qtubuntu/pull/18 for more info.
