Since 10.0.5 dropped I sometimes get a pretty weird form of lag, usually occuring upon entering a new zone while dragonriding. The dragon stops reacting to all abilities, and I can not dismount nor use any of my own abilities. I am however NOT getting disconnected, even 10 minutes after my game stopped reacting to any of my inputs i am able to receive and send chat messages in my guild, /s chat as well as friends on Blizzard ID.
I did a speedtest and tried disabling my addons and can safely say that neither is the problem.
Edit: I also can not close the game through any means except for the task manager or ALT+F4.
