The bug
The crosshair used in F3 screen (the one with the 3 colored axis) is not centered properly on the game window, compared to the regular crosshair.
This can cause missclick when placing/breaking block when F3 is open.
The issue is more problematic on a big resolution screen.
How to reproduce
Play with a big enough resolution screen (1440p at least to notice the issue, 1080p is still visible but not that annoying)
Notice that when toggeling F3, the center of the F3 crosshair is not aligned with the regular one.

No, the issue you linked describe an issue with the regular (non-F3) cross-hair being misaligned by a few pixel from the actual center of the screen.
My issue describe the even bigger misalignment of the F3 cross-hair.
But this is definitely related in some way.
Can confirm in 23w43b. I would argue this issue is seperate to MC-157252, and should be marked as related. The F3 crosshair is even further off-center than the normal crosshair:

Does MC-157252 describe your issue?
