Instancing sprite is glitchy

[Coder2195Text]

Godot version

Godot 4 Beta 4

System information

Ubuntu 22.04 Running on Vulkan Mesa Intel® UHD Graphics 620 (WHL GT2)

Issue description

Instancing a sprite is pretty laggy, and if you look at timestamp 0:29, a random missile trail pops in and out of view (THERE IS NO MISSILE ATTACHED TO THE TRAIL)

I have shown in the video I have performance mode on.

If you look at my code, I am using threads as well (Scripts/GameScene/Player.cs line 25)

Could you please provide an MRP? An MRP is a minimal reproduction project. Essentially it contains the fewest elements possible to reproduce the bug (more info here).

While it may be helpful to have your entire game available, it is not fair to ask contributors to debug your entire game to figure out a) if this is a bug in your code or in Godot and b) where in Godot the bug exists (if one exists at all).

To start, you can try to isolate elements of your game that you think are causing the problem. You mention that you are using threads, threads are a powerful tool but can be challenging to get right. When making an MRP, you should try to run your scene without threads and see if you can still reproduce the issue.

My game isnt a full on game yet, all it is is basic movement and firing of missiles, nothing more. It should be pretty minial

The reason I used threads was this issue happens without threads, so threads is eliminated as an reason
Particles arent the cause, because I disabled them and issue still happens.
The glb sizes are only a few kb, so it cant be vertices.

I disabled lighting as well.
Still doesnt work

I dont see anymore things that could be lowering the fps everytime a missile spawns.

The stutter is a duplicate of #61233. The particle issue is likely a duplicate of #56691.

Its not about the particles, cuz I ruled those out

As for duplicate of #61233 is there any current way to fix it? Because on the issue there isnt a solution that I see

I found that after firing a missile, these errors are added to debug

E 0:00:03:0209   compute_list_bind_uniform_set: Condition "!uniform_set" is true.

Like in 3.x, you can show the material for a single frame when the project starts. This can be done behind a solid surface (if no occlusion culling is used), but it must be done in front of the camera so that the object isn't culled outside the view frustum.

Can I leave it for the whole duration? because I might attach 1 missile under the belly of the airplane

so can I show for more than a frame?

I tried placing a missile under jets belly, that causes TREMEDOUS lag

[Coder2195Text]

oops, it was layer issue I see

[Coder2195Text]

I found out why its glitchy because my missile is stuck in the plane and it lags trying to free itself
Since I forgot to change the physics layers
