[wpe-webkit] Encrypted Media => WebGL FPS Drop ?

[Andrea Giammarchi]

Hello there,
  I've successfully built WPE WebKit with all the things enabled, including
encrypted media and Qt API. But even without Qt API (previous build), I've
noticed that this demo [1], that used to spin at roughly 60FPS via weston +
cog at 720p, now spins at roughly 40 FPS.

Platform: Raspberry Pi 4 (either 4GB or 8GB)

Is this something expected, or maybe unrelated? 2.28.3 is the current build
I'm using, and I'm just wondering if it's possible that encrypted media
interfere with WebGL performance.

Thanks in advance for any hint/info you could share.
