When opening the accessories menu in Vivecraft, the entire screen will freeze except for a tiny sliver in the bottom-left of the display.

This is incredibly disorienting within the VR headset. See video for example: https://www.youtube.com/watch?v=7TdR2rvs0DI

Accessories 1.2.18
Vivecraft 1.2.5
Minecraft 1.21.4
Fabric 0.16.10

Idk what to say to this as this issue may need to be raised on Vivecrafts side and could be a issue with owo-ui either requiring some changes within Vivecraft or owo

As shown here in this Alloy Forgery issue here, its a similar bug related to owo UI. This needs to be reported to Vivecraft for anything to be done.

Thanks for the clarification. I'm reporting this to the Vivecraft team now.
