Weston repaint frequency?

Hello all,

I seem to have an issue, that whatever I try to run on my weston backend, I never seem to exceed +- 40fps. 

That can also be seen by running the weston-simple-egl test.

When I run weston-simple-egl -f, so fullscreen, I get upto 27 fps.

But, when I add -b, so weston-simple-egl -f -b (Don't sync to compositor redraw (eglSwapInterval 0)), I get a stunning 175 fps!

So what is limiting the weston refresh rate? I'm running on a IMX6D, industrial grade, morty yocto, weston/wayland 1.11. My fb settings are:


mode "1920x1080-60"
# D: 148.500 MHz, H: 67.500 kHz, V: 60.000 Hz
geometry 1920 1080 1920 2160 16
timings 6734 148 88 36 4 44 5
accel false
