The shrinking triangle that the Predator sees is not centered on the spot the three dots are actually on. The triangle is set just below actual center. I have tested this at a few different resolutions to be sure it was not something with my system. 1920x1080, 2156x1440, and 3840x2160. The screen shot was made at 3840x2160 from a video I recorded with OBS while playing the game at 1920x1080 full screen, so sorry for the bit if blurriness. This is right before the plasma cannon overloads and automatically fires. In it you can see that the center of the triangle is well below where the plasma blast will actually strike (at the 3 red dots).
Not a huge issue, but I know at least for me the moving triangle catches my eye and I tend to follow it instead of where the plasma cannon is actually aiming. Thank you.
Edit: This may be happening only in Private matches, as it did not seem to do this in a Public match I just tested in.
