Since Release 8.3 on live my game application began to freeze often, after which the window begins to spontaneously change its size (window full-screen mode), sometimes without returning to its original state before freezing.
Also, the use of RAM suddenly increased from 2GB (normal RAM use up to 8.2.5) to 4-8.5GB, as a result of which the system goes into black screen mode.
I talked with other players in a few discord channels and some have the same problem, even for people who have a fresh computer “just out of the box”.
UPD: right now i use laptop with 16GB RAM, SSD250GB (windows+WoW), nVidia GeForce 920m, i7 - issue wasn’t reproduce in 8.2.5
Rauko, my PC was crashing, changing Direct11 to Direct11 Legacy solved all my problems. I read this fix in another thread last Friday - the change is done in game in 30 sec (advanced setting).
gonna try this during next hour, need to get back home from office - i’ll update this post how this finished and mark your answer as a solution if it will help
