Game crashes on alt+tab with NVIDIA GPU #766
Description
This is a documentation issue to note a rare crash thats happening for a small amount of users, and is currently unsolveable from the mod
Bug description
For some users the game will crash if some unknown conditions are met when using voicechat and an nvidia gpu, in most cases its more common when sodium is installed, but it is not required
not much is known about why it crashes, but the issue seems to be caused by the nvidia drivers,
Potential workaround
setting the following setting to prefer native solves the crash for some users, but not everyone has the minecraft profile to configure this setting in
the crash will look like the following
