thanks for your response, Mark
that’s exactly what I did to work around the problem, I got the lumetri from the effects panel. sometimes i keep working in the standard editing worspace and add the lumetri panel from window menu. that does work with me but still, premiere crashes always when I open the comparison view.. you know how important is it. it’s irreplaceable.
I have already updated the graphics driver to the latest version.
so, what do you think about my hardware??
