Screen Space UI looks jagged in VR (oculusGO)

Hello, we are developing an app for the oculus go headset and are experiencing issues with our UI. We have a screen space UI canvas with different elements (buttons, images, sliders), and everything looks really jagged around the edges. We can see that the antialiasing works on 3d elements in the scene and when we run in the editor everything looks fine but on the device it dosent work. We will really appreciate any help or general tips for making UI looking better on the platform. Thank you in advance!
