Hi Yuri,

I would appreciate your feedback on this problem. Does killing Weston help ?

Thanks.

Felix.

Hi Felix,

Yes, thank you! Killing Weston helps a lot - mouse is not lagging any more.
The button look different though, kinda flat, but I suppose we can live with that.

On a general note, looks like Weston is either not optimised, or doesn't work well with AM33 hardware?

Weston consumes a lot of CPU, so unless you have a compelling reason to use it, you'd better run QT application with eglfs.
