This happened right after exploding in Sedina D-2 and respawning in D-14.

Linux 4.4.0
Renderer: Gallium 0.4 on AMD BARTS (DRM 2.43.0, LLVM 3.9.0)
Version: 3.0 Mesa 11.2.0-devel (git-e976860)

It keeps doing this every time I respawn in Sedina D-14.

Re-homed at Sedina L-2 and it doesn't happen. Must be something up with D-14.

I am also having this problem on a WIndows 10 machine with a AMD FX-something processor, AMD R9 280 and 8 GB of RAM

To further expand I can confirm this happens to me in Sedina D-14 but not L-2, also, if I turn off multithreaded via the config.ini I don't have any problems. This testing was done with no addons of course.

You're both having the screen clipped off and offset like that?
What VO video driver settings are you both using? I am unable to replicate the problem on my linux VM with GL Reference and GL4 drivers with multithreaded=1

Each crash is a little different, I have had the offset screen clip a couple times, once with the logo and once just a part of the background, more often I just get stuck at a loading screen, once it finally loaded after 5-8 minutes, most of the time I just force close it.

But I am on a windows 10 system with the DX 11 driver.

It clipped the loading screen and hung there like that every time i died and respawned in Sedina D-14. The screen it froze on wasn't always exactly the same, but it was some combination of black and a chuunk of the loading screen and chat window.

It's worth noting that every time it happened,, i had the chat box open typing after dying.

Linux 64bit GL4 with multithread on.

Same here, except it freezes at the loading screen and I have to kill VO and restart

New client patch 1.8.367.3 is released that should fix the problem. The bug was related to shadows and multi-threaded rendering.
