{Bug} Stuff stays on screen, ruins game!

I get this horrible problem, and it's probably already been noted, but I want to repeat it because it just plain ruins the game. When to much is going on, for instance with a mass of aoe attacks, the damges and events that show up, like Level up or -115, stay there. You can't get rid of them unless you do nothing for a while. When this problem is occuring, nothing else can really be read. Descriptions of items upgrades or powers from there respective menues no longer have text acompany them. And of course, on top of all this, you really can't see and therefor target enemies or other things on the field.
