1080p Content with stable framerate possible?

[smarthomeagentur]

I would be interested in any success playing 1080p content via WPE. I tried OMX Player with great success (perfect framerate on Pi3, 50 fps content works). So the hardware works fine but with WPE I only get stable framerate with 720p. Higher resolution leads to framedrops. Is it a general problem with Webkit on Raspberry/Balena or is there any chance to get 1080p HTML5 content stable in future?

Thanks for the effort and best regards

Daniel
