Backtrace With Terminal Output (tid,seh)

The game crashes seemingly without doing anything in particular, though most
often it has happened after having moved from an area to another, or right
after having entered the game world, the player having gained control of their
character.

Usually after having moved to a different area, the crash occurs when moving
the player character or/and the camera.

It has also happened while the game window was in the background, not active.

Perhaps somewhat interestingly, it seems to always crash in '0x79db5d60':

Backtrace:
=>0 0x79db5d60 in libnvidia-glcore.so.378.13 (+0x14d3d60) (0x676cf844)

Reverting "wined3d: Do not preload the buffer in wined3d_buffer_unmap()."
(6fd212818d6ade9d571aba1566b5e56ce594b01b) seems to fix/avoid this.
