I use dual monitors.
Load blade , (i have all panels but render , on monitor 2. Render and main blade panel is on monitor 1)
click on a panel in monitor 2.
resize render / main blade window in any way, including opening a panel etc.
Black screen /freeze
I'm not certain if this is related to dynamic detail mentioned above, I cant repro that, but this is just the way it happens on my setup.
EDIT:
okay, this does only happen AFTER logging a character into the game. We do have dynamic details in all areas so whether or not that is the issue or not I dont know, the above stated process will give a black screen every time on my setup.
