Everything Looks Black and White Mac Silicon

[AtlasLinden]

Environment

Second Life Release 7.1.10.10800445603 (64bit)
Mac M2

Description

This issue is being reproduced but reportedly only on M2 macs: #1852

Reproduction steps 1. (I've not been able to repro this on an M1. -Dan)

1. Visit this location: Panfield
2. Change the reflection coverage settings from "Manual" to "Full Scene".
3. Wait 10-20 minutes.
4. Zoom in and out on a house or avatar, dragging the camera to force the environment to re-render or reload.

Reproduction steps 2.

1. On a MacBook Air with M1 chip.
2. Set Preferences > Graphics > Quality & speed slider to Low+, then open Advanced Settings and change Reflection Coverage to Full scene.
3. Visit http://maps.secondlife.com/secondlife/Ambrosia/43/143/35
4. Set World menu > Environment > Sunrise

Observed: Parts of the nearby lighthouse, trees, and waves will turn gray or black.

Expected: Normal colors.

Note: This may be a clue - If you create a new Day Cycle and open it, this bug will repro at the keyframes but not between the keyframes.

See #1852 (comment) for more info

is this related to the time of day on the environment day cycle settings? might that be why waiting is part of the repro? do we have info on what the Apparent Time of Day is when this is being seen?

[AtlasLinden]

The region is using a 24 hour EEP setting. Looking at Igor's image on #1852 (comment), the environments Apparent Time of Day is around midday when this issue is triggered.

Just retested at approximately 8pm apparent time and issue still present (white out after about 5 mins)

This issue has been linked to a Canny post: Scene turns black and white on Mac M2 🎉

I believe issue is also occuring on M3 Macs (from a friend who mentioned), Appreciate not so many of those around to be able to test with :-)

Please can we change the title of this issue : I can confirm occuring on ALL mac silicon machines (a friend confirmed problem existing also on M3) not just M2 - I tested today on my M1 Max MBP at this location http://maps.secondlife.com/secondlife/Ambrosia/11/152/35 (i.e edge of sim .. looking at buildings from flying in the sky pos) and the white out continues to occur.
This is clearly an issue for Mac Silicon - not sure if ok on intel Mac, but im sure you will be looking into this as a priority given the increase in mac silicon machines vs intel - thanks

Title is still incorrect - please can this be corrected. The issue is affecting ALL silicon Macs - would also appreciate an update if possible please. Thanks

Hi. thanks for updating the title.

So i guess this has been pushed into the long grass? I didnt see any updates / fixes noted on Extra FPS notes? Just to re-iterate, this is affecting ALL mac silicon machines and at several locations.

I also note that no-one has been assigned to this yet - can you explain why please?
