QDS Oulu - 2025 Week 15/16
Description
- Create new 3d project
- Add e.g. glass material from content library or create a new material
- Repeatedly drag materials from material browser into navigator or other views
-> Sometimes the entire UI freezes after the drag starts. Unclear how to reproduce this reliably, but usually happens within a <10 drags if it's going to happen. However, sometimes it won't happen at all until QDS is restarted.
Stack trace of the freeze:
