I concur, about 2-3 weeks ago an update occurred, i think the one prior to adding the WYSIWYG editor. Now if i minimize Slack in Windows then maximize it again, I get 5 seconds of black screen before it displays. This happens at work, home, and my laptop. Performance has never got better for me, just worse, but I keep hearing about performance improvements?!?
