Just got an HP 710 wireless mouse and only experience this issue in battlegrounds. At random moments, the pointer will either jump in tracking speed or will freeze, only able to move left and right but not up or down. The only way I can temporarily fix it is to turn the mouse off then on again. It’ll be fine for a minute or so before do the same thing over again.
This only happens in battlegrounds and arenas. I’ve tested it without addons and it still occurs. Any advice is appreciated!
