Mouse keeps flicking to top left

OK. When I’m shooting, any hero, my mouse randomly teleports to the top left causing my character to aim top left. This is really annoying and makes my game unplayable. To my knowledge, this is only for overwatch. Testing a few other games for this but this doesn’t make sense and really is irritating me. I’ll try to post a gyazo or a gif of what I mean.

In essence, when I’m shooting, my mouse/cursor goes to the left and it throws off my aim.
(I’m not sure if this goes in bug report or technical issues)

its happening to me aswell, only in overwatch i tried other games.
changed usb port, cleaned sensor and mousepad, repaired the game but still keeps happening. it started like 1h ago, when i played before everything was okay.
kinda glad im not the only one with that issue!

i think some additional infos here could help the devs fixing the issue:

  1. (annoying, but u kinda have to ask) did turning the pc off and on again have any effect on the issue?
  2. did the bug appear mid-session or immediately as you started the game?
  3. what changed in between the time you last played without the bug and its first appearance (any updates or patches, maybe also in the background) ?
  4. what is exactly affected by this? like is it only leftclick, or maybe rightclick as well? maybe its only projectiles?that stuff…

the more they know the easier they can solve the problem
