This two pictures were taken from the same spot looking at different directions. When I moved the camera angle a little bit higher.
But it also happens with other 3D arrows too, like the camera’s one:
First, as I said, the pictures were taken from the same spot.
Second, if you just get closer to the origin of the arrow, it doesn’t grow bigger on your screen.
Do you by chance have any steps to reproduce the issue or are you able to reproduce this in a new project?
So far I haven’t had any luck and without steps for it to be a reproducible issue I won’t be able to submit any type of ticket for this.
If it is not happening in a new project you can try deleting the Saved, Config, and Intermediate folders from your project folder. This will wipe any project settings or editor preferences that were set.
Looking at this issue, it’s been around for each build that I have currently on my machine 4.12 - 4.15. It looks like it’s a clipping issue when you’re within the area of the icon that causes the static mesh for the arrow to snap larger which is only noticeable when moving around the world at these low speeds.
The workaround here would be to use the hotkey for Game mode (Press G) or to hide these actors when flying around the world.
I can enter a ticket for this if you’d like, but from the looks of it, the ticket would be marked as “Minor” or closed out as “won’t fix” or “by design” in the end since it can easily be worked around and is not a game-breaking issue.
I guess it would be good to have a ticket about it even though I agree it is a minor problem (but definitely not “by design”), but could be proper job for testing an intern, or for a lazy Friday 3PM, or whenever it fits
