(I have had this issue for as long as I can remember but never bothered to report it before. No one I’ve spoken to so far seems to have a similar problem, and while I can reproduce it with 100% certainty, I am unable to find anyone else who can.)
When playing a roblox game, if I hold right-click to move my camera around and then release it to move my cursor, my mouse movements will sometimes be completely ignored until I stop moving the mouse or change direction. Mouse button presses are still registered properly.
I must be moving my mouse the whole time, when I release right click while moving my mouse, my mouse will sometimes freeze.
Panning the camera horizontally or vertically will not cause the bug (I am holding and releasing right-click while moving the cursor in the same direction overtime): https://gyazo.com/6f29046dc518d55a6249c95b9c9c4054
Panning the camera diagonally will cause the cursor to stop completely until I stop moving the mouse or change direction (again, I am still moving the cursor after every camera pan): https://gyazo.com/4cb6f18d8b330b21d89119812e858542
Using shift-lock rather than right-click causes the same issue, with the cursor teleporting to the center and not moving until I change direction: https://gyazo.com/bb853ab960c8b402168f9578ee77ffb1
Note that the bug does not occur in ROBLOX Studio, whether using the Edit mode camera or when playtesting the game. It however happens on the ROBLOX player, on every game. This bug does not happen outside of ROBLOX either.
So far I have tried reinstalling the player, using a different mouse or a touchpad, or updating their respective drivers, to no avail.
Dxdiag available upon request but I don’t think it’s needed.
