My scene contains just a ScrollContainer with 9 TextureButtons inside (Game Inventory). The project works very smooth in Desktop (60 FPS). But In Android FPS is below 10. I tried so many optimization in project settings but nothing works. still no luck.
GLES3
Godot version 3.1 stable

UPDATE
I finally found that the performance drop is caused by 'StyleBoxFlat' in property 'customstyle'. I replace it with Textures, now I got 60 FPS in Android. I don't know why 'StyleBoxFlat' causing this, may be a bug in Engine. Thanks
