Just tested in RC 1.19.1.3 still a problem
1. Request the Two HUDs from me.
2. attach object "HUD v1.1.8.1 RC1 testA"
3. wait for texture to load
4. attach object "HUD v1.1.8.1 RC1 testB"
5. right click and detach The Top one which was "HUD v1.1.8.1 RC1 testB"
6. Did a few of the bottoms turn a solid black
Look at attach file for example
The only fix is to Detach all HUDs with this problem and relog
Then Attach them again.
This seem to only do this on Nvidia environment
