Textures not loading and staying grey on Mac Viewer on M1 Max

[canny[bot]]

Using the Atlasaurus build :

Second Life Release 7.1.9.9620320242 (64bit) on Apple M1 Max

(using as it contains a fix for the showstopper OpenGL buffer problem on Apple Silicon)

• I have not noticed this behaviour before on the Release viewer, but textures are very slow to load from grey and many 'stick' completely without ever loading.

• Go to a content rich region such as a Linden Homes region, for example somewhere in the area of near SSPPigadi

• Getting random 'stuck' grey textures after a while, some of which eventually render after a number of minutes, but many never do. Some may be on my avatar, or nearby content if I've cammed away for a while.

• Restarting may bring them back but grey out a whole new set after a time.

• The effect may take some considerable time to kick in, but when it does it sticks around, and more and more textures become affected.

• This issue has been heavily linked to PBR Firestorm on Mac, where I see the exact same phenomenon on a resident alt, but this is the same behaviour on our viewer.

Extra comment from Garden mole: I have been monitoring the relevant thread in the Firestorm Jira concerning this same effect. One point which has come up repeatedly is switching the debug setting : RenderGLMultiThreadedTextures to TRUE ( It is set FALSE by default ) I have done this on Atlasaurus and so far the problem has not re-occurred which is promising.

Whirly has mentioned that Firestorm users have been toggling this debug setting to stop this issue from occurring: RenderGLMultiThreadedTextures and that this may be a fix for the issue: https://github.com/FirestormViewer/phoenix-firestorm/commit/a447221d66d67bc2be3d8b62942e5a4dcf869b6f

downgraded this from showstopper for the time being. this seems to mainly be a problem when FPS are very low, and our efforts are better directed at fixing those FPS stalls
