UI Image plus Animator glitch?

Hello everyone,

I’m dealing with what seems to be a glitch of Unity, maybe related to how it handles filled images for UI.

So the problem is, i have this UI image on Image Type = filled (radial 90 bottom right) + an animator component to animate the sprites, but as soon as i change the value of Fill Amount to less than 1 during the animation, the image gets glitchy…and by glitchy i mean the image slightly and quickly moves out of place a couple of pixels DURING the animation multiple times…it just gets jiggly.

This obviously makes my UI bugged and useless.

In wireframe mode, i noticed that Unity actually changes the geometry of the image in order to achieve the filled effect changing, of course, its boundaries.

Could this be the cause of the problem? Or maybe something else? Have some of you guys experienced something similar before and came out with a solution? I tried to search the internet and unity answers, but found nothing so far :frowning:

Unfortunately, still images can’t give you an idea of the problem, but still…
The upper-left curved bar should fill according to the player energy, and the flashy white animation gets played from time to time. The filled bar gets jiggly during that flashy anim.

It’s not a Unity glitch!
For anyone interested in the solution, i actually managed to solve the issue by simply SUPER cleaning the transparent pixels of my png sprite sheet.
I had a couple of (VERY few) non 100% transparent pixels laying around the image (they were at maybe 1% opacity, impossible to catch by eye).
Once i cleared every one of them, i re-imported the new sheet in Unity, updated the animation frames with the new sprites and voilà!
