So, after several hours of playing with multiple clients running I had one crash on docking in to a station.  That's not so much the unusual part, although docking usually doesn't cause crashes for me and that is pretty rare by itself.

The weird part was after I hit okay to submit the report, 2 of my other clients glitched while 2 other kept running unaffected.  The two that messed up started .. it's hard to describe, they were all docked in a station, the same station, and all of the UI windows and everything would like turn off and back on again.  On one client it did this very quickly like 3 times a second and on the other one it was slow like 1 a second.

Killing and restarting the clients fixed it but I thought it was really bizarre and maybe related to the insane stuttering I get on terrain which gets worse the more clients I have on terrain near each other (4 is basically an unplayable slide show and clicking on things is the hardest part because its like the screen is refreshing more slowly or something and it misses my clicks and they don't register properly on terrain or other bots or field cans or whatever).

EDIT: I should add that I thought that the bug report crashed client was the one causing the flickering so I killed that one before it sent the whole dump - but since that didn't fix the other 2 clients I restarted them like I said above.
