some of the recent changes broke weston (mesa from 2019.09.24)
I am testing lima with mesa master form 2019.09.24 with weston 7.0
and its all just wrong :) Windows are partially redraw, but if I run glmark all works fine but I don't see weston background or other terminal windows If they don't redraw.
maybe it is related to partial to EGL_KHR_partial_update
I am testing on odroid C2
on linux kernel 5.3.1 with https://gist.github.com/anarsoul/22532572cd139f7622c55c8f40b3c5ad
