When I use Slack, over time it creates more and more tabs (in my alt-tab view) that are called NotificationListView, but that I cannot either select or close them.
It starts to clutter my alt-tab view, as after only a short time I'll have ~10 of these tabs. Is there a way to prevent this from occurring?

I'm experiencing this issue as well. I'd hazard a guess this is a bug with the application itself and has to be filed and solved as such.
I've contacted Slack and they sent me this reponse (emphasis mine):
I've installed the quick fix which minimizes the problem by collapsing all the items in the alt-tab menu down to only 1 lingering notification.
Until then, the only workaround to get rid of all lingering items seems to be to close the application and restart it.
Apart from that we'll just have to wait for a new version.
