How severe is your issue? Major impacts to gameplay
What happens when the bug occurs? Your crosshair jumps much further than expected.
What should be happening instead? You should be able to snap to where you intended to aim.
Steps: How can we find the bug ourselves? To make the bug very strong and easy to find set ADS sensitivity multiplier for a sniper to a high value like 8, then try to move your mouse while going from hipfire to ADS. Compare this to plain ADS or hipfire. This problem gets worse the higher the adjustment number is and occurs for both individual scope multipliers and for the overall ADS multiplier.
