Non-stop wow errors in dalaran

I'm using the "old" WOTLK client, Large Address Aware yet i still get WoW errors in dalaran..
my specs are:
i5-8300h
gtx 1050 4gb
8gb ram
HELP ITS ANNOYING MEEEEEe

had same thing, downloaded "new" WOTLK client and it's ok now

but maybe someone got better option?

Scale down the view distance and pretty much every other slider to medium. That fixed all wow errors I had.
