what is the global gui refresh metro ?
that is/was my (temporary) solution for the slow gui: a metro at 8 hz sending bangs to a global send and a [f] receiving these bangs before every slider/number/ which is updated via midi-ctl, counters, sequencers, whatever. while directly connecting a few midi-controllers to sliders could easily stall the gui (when the knobs are moved), this solution looked not very beautiful, but caused no dramatic cpu-spikes, even without 2d hardware acceleration.
and do other graphics cards have different options besides ShadowPrimary that allows fast access to pixel data?
i suppose so...
Can look it up but seeing that you have recently been dabbling in it...
only with my radeon card under linux, until i had success with the settings in xorg.conf.
Option "AccelMethod" "glamor" Option "ShadowPrimary" "on"
