Happens with Logitech G303 wired mouse, or Apple Magic Trackpad 2. Happens inside the game or in the main menu screens.
Basically, any time the left moue button is held down (e.g. like you would do to to drag across a selection of units), moving the mouse is EXTREMELY slow/laggy. And it’s not even slowed to a predictable degree, it’s just absolutely broken because sometimes a drag of 6 inches produces almost no movement, and other times it will go across the whole screen.
I compared it to dragging on the desktop and neither the trackpad nor the moue have this issue.
What’s going on here?
EDIT: Quitting BetterTouchTool seems to have fixed this. We’ll see if this is a lasting fix.
EDIT 2: There’s still a problem where, if at any point I use middle-click-drag-to-scroll, then thereafter the cursor refuses to move DOWN unless with a big motion. Happens with trackpad or wired mouse—_after_doing a middle click drag scroll.
