Stencil Buffer is fucked on current gen (possibly earlier) Radeons
If you are using a recent and possibly earlier gen radeon, then SL's stencil buffer fucks up. This leads to a variety of issues, such as selection outlines when highlighting things in edit being very fucky and blinding, and hover text being visible from a distance through multiple barriers.
Drake knows more about this and the nitty gritty about it then I do. He suggested one of the outsourced labor sources that LL turns to did an optimization that fucked stencil buffering for AMD if I recall correctly.
I have only tested it with my current GPU do not know if it is limited to a particular model range or not.
Steps to reproduce
http://maps.secondlife.com/secondlife/Olive/31/69/58 Go here with a AMD Radeon RX 5700 XT or similar hardware. Go into first person and look through the center of the dance floor from this position. Hover text is visible.
Visit the same area with a nvidia board, and first person look through the center of the dance floor from the same position. Hover text is not visible.
Right click and edit complex geometry with a AMD Radeon RX 5700 XT
Compare the same action against doing so with a nVidia
What is the current bug behavior?
Stencil buffer fuckups is causing stuff that should be obscured by geometry to be quite visible
What is the expected correct behavior?
See reproduction steps, the nvidia behavior is expected.
