Mouse cursor drifts upwards at all times

[Former user]

Whenever I'm in the game, the mouse cursor will continuously move upwards. I don't have a joystick or control plugged in, just the mouse. The only thing that'll stop it is pressing escape to pull up that menu, but it starts all over again as soon as that menu is closed.

Can you tell us about your system? What operating system, what screen resolution? Does this happen in fullscreen or windowed mode or both? Does it recur if the window size is changed?

Reprioritising to minor because this seems to be a very rare bug, and can usually be worked around by changing the window size.

Having the same issue on a 2015 Alienware 13". Mouse plugged in or not, the cursor continually drifts upwards.

@TomasFitz as above, can you tell us what operating system you're using? What screen resolution, and does this occur in fullscreen or windowed mode or both? Does it recur if the window size is changed?

Since we cannot reproduce this on our test machines, it's impossible to diagnose without at least some information from issue reporters...
