Issues with release 4.6.0

[lousilver]

Hi,

I updated FG and played this past Sunday. No issues. Last night I updated and played with a different group. I can no longer delete single pointers on a map (really annoying as the GM). Various players were having connectivity issues (generally laggy for everyone). When I was scrolling the action tab of a character after everyone had disconnected (a lot of spells), artifacts (e.g. text) were briefly appearing outside of the character window/gui, dropdowns were not rendering properly, etc.
