Can someone who has tried this tell me whether two particular bugs that were present throughout the life of Plasma 4 have been fixed (OK, you may not think these are bugs, but I sure do: I can't imagine how they were ever allowed to persist, since to me they seem to violate pretty basic requirements of GUI behaviour):
1. If one has a menu present (for example, by pressing the K-Menu button), does an incoming notification still cause the menu to disappear, so you get the delightfully random experience of clicking on whatever happened to be under the item you were about to click on?
2. Can a single misbehaving plasmoid still cause the entire desktop to freeze? (This typically happens to me if the network connectivity is lost: poorly-written plasmoids that need network access can block and cause everything -- not just the plasmoid in question -- to freeze.)
