Repo:
- Go into a roblox game
- Move your cursor somewhere
- Click
Tested on multiple computers and multiple game instances, this didn’t occur yesterday.

Don’t notice this. Do you have a gif?
I can try to record it, one second.
Is it possibly because your mouse sensitivity is very high so when you click it detects a slight move as your press down?
I’ve changed the settings of both my mouse dpi and in-game sensitivity, it doesn’t occur anywhere else but in roblox.
Can confirm. This seems to only happen for the first click after moving the mouse. So if you move your mouse and click four times at the same spot, your cursor will only move a pixel upon the first click. But if you move the mouse afterwards the behavior will reset and your cursor will once again move a pixel when clicking. The cursor also seems to move in a random direction which makes me believe this is some kind of rounding problem.

I can also confirm by programming a key on my keyboard to do the clicking (to prevent mouse nudging). The moment seems to be based off of the direction the mouse was moving.
It’s very frustrating when playing @Simoon68’s bowling game because it requires pixel precise throws.

I can’t seem to repro. Can anyone else view that video? no browser seems to work for me
The url to the video is invalid now, it worked before. @maplestick should re-upload it or upload it to the forum instead so it won’t expire.

I thought it was just my game. This messed up one of my tools that needed to click in the same mouse.x and y twice. I changed it to detect camera cframe changes instead, which seems better to make sure the camera wasn’t moved.
I got a few dozen reports of this last week though. I didn’t see the mouse jump a pixel on click, but I was printing the mouse x and y and that was changing (without moving the mouse and only clicking.)

It’s been over 5 years and this issue is still present. Please fix it or give us an option as it’s incredibly annoying.

Can confirm, this is STILL happening. It doesn’t seem like a problem to me, but people still want it fixed

I was under the impression that Roblox might have added this intentionally, with the goal of combating basic macro scripts.

I don’t seem to be able to repro this, and never have noticed it, even when clicking on Buttons, aside from small nudges that are my own fault. Is it possible this is a machine specific issue?

This is what happens in practically any game for me.
I’ve made a small gui to show when I’m holding left click to showcase this issue.
