Game crash with 2nd monitor

[maxcodk]

Hello! Twow, using vanila fixes
Game gets fps drop for ~1sec and crashes without mistake in some instances and raids(BWL and NAX mostly)
the problem disappears if i unplug my 2nd monitor for some reason
the reason i think this can be caused by vanila-tweaks is that after reinstall fresh client i downloaded every addon exept vanila-tweaks and now it works fine
any ideas what can be the reason? may be some certain settings?

i also experimented a lot with WTF folder, deleted other data addons

Try setting /console SoundSoftwareChannels 12. I've heard reports that setting this to 64 can sometimes cause crashes... though the fact that the crash doesn't happen if your 2nd monitor is unplugged is strange.
