Mouse arrow moves by itself

[davy_panis]

Just done the new update to 0.17.52. And at the start of the game, my mouse pointer began to move slowly out of sight to the top of the screen. if I moved the mouse pointer to where I wanted with the mouse, this will work. But immediately the mouse pointer moves slowly to the top of the screen.

The link above is a very short video that I made of the problem.

For me (working in electronics and programming) this sounds more like electrical interference. Something like: High CPU usage -> high power demand -> high ripple on power lines. This propagates by wire to mouse (from gpu and cpu i assume this is stationary pc) and by coincidence this ripple in power supply makes optical sensor in mouse to detect some spurious movement. This can be easily tested: run factorio, move coursor to lower left corner (as it is moving top-right) and just unplug mouse. Factorio should not be able to detect that mouse is disconnected, but if cursor stops moving, then issue is within mouse itself.

OK thanks.

Such an interesting thought. Please post your results of the unplug test!
