Empty Scene causes fps drops due to rendering

This i a almost empty Scene, only 2 TextMeshPro elements to render, and for the most part the fps are just fine, but every now an then i get those random fps drops due to the rendering.

My System: - Unity 2020.3.30f1 - On Galaxy Note 8 (Android) - Scripting backend: IL2CPP

Unfortunately, i cant see into the GPU with the Profiler, since my phone doesnt support that. I ve switched between multiple Unity verison with this project, maybe something broke? Well i dont know im desprerate at this point
