I think we have two separate problems here, but let’s see: @ArtInvent, let’s see if this thread workaround fixes your problem? Layout Viewport Refreshing Crashes Still Occurring - #7 by ArtInvent
I can’t repro it on Win or Mac, but perhaps my test models aren’t big enough, or with a lot of style files.
@glaroche_edvance, private message me with anything that might help us reproduce this issue. And see @DanRathbun 's suggestions show anything, and also try not updating models from a blank page per the above thread.
