Particles not playing on full screen?

[Qbanyto]

Odd one here. so I have a specific Ui particle playing on my games life bar. I have a specific camera rendering it. All works perfectly fine when windowed or even when expanding that editor to enlarge the game view.

But if I double tap the “game” tab to go full screen or “play maximized”, this specific particular does not play. But if I exit full screen, it plays just fine.

any ideas?

Hi.
can you try if you center in the canvas if it still does not show, it might be some anchoring issue.

else it might be shader issue

[Qbanyto]

well, here is the weird part.
I have a dual monitor set up and it if put it on full screen on the second monitor, it works fine. but on the primary monitor, the particles won't play in full screen.

Hmm.
You might want to ask on the unity forums.

I did no one is answering but i found the issue.

So when I use the 16:9, 16:10 or FullHD resoultions on the editor, it shows fine.

but when I change to any of the higher ones (WXGA, QHD 4KUHD) then the game object of the particles gets SHIFTED to another location. Which is odd because this particle game object has a UI parent game object that doesn't move. why is this child being effects only and on these particular settings?

Its on the same layer as the parent object as well (UI). Anyideas? will this happen on build?

Hi.
A particle system is not a ui object.
Try placing a cube similar like you placed the particle system and see if you have the same result.

Another thing you can try is to use :
Rect Transform Screen Point To World Point In Rectangle
To position the particle.
(probably best to place the particle outside the canvas.

Hmm. I cannot seems to get this working with the "rect to transform.." method. What do i put in the x,Y values? do I use the main camera in that option?

is the particle under "world "or local" when is emitted? It could be when you change resolution, the position it emits from get changed. Or something could had locked it when is activated, and once it gets turn off and you changed resolution, the particle doesn't recognize the new position.

[Qbanyto]

thats exactly what happens. In the editor i can see it change to a different position. But it ONLY happens with the higher resolution ones (WXGA, QHD 4KUHD).
The PARENT object (lifebar) moves too But, I can still SEE it on the game view. why is this happening? it seems WXGA QHD and 4K all have different positions.
