Hello,

This bug has been around for quite a while, for some reasons, shadows may be pixelated on some parts or their edges.

I really don’t know why this happens, this bug can occur in any game, both on shadowmap and future lighting technologies.

System Information :

OS : Hyperos 2/Android 15
Specs : Snapdragon 7s Gen 2 - 8Gb RAM
Device : Redmi Note 13 Pro 5G

Roblox Version : 2.658.460

(Please note this also occurs on Redmi 9T)

(As we can see here, the left part has normal shadows but the right part doesn’t)

Expected behavior

The shadows shouldn’t be pixelated.

Looks like Roblox on mobile is trying to optimize your performance by applying wrong shadows artifacts ,if your device is medium-end

Why not deleting the cache?

That’s a bug, my device performs well and it has nothing to do with the cache or performance, I probably reinstalled Roblox multiple times since this bug has been around for years.

(This occurs both on my old and new phone)

What graphics level is this occurring on?

5

Any graphic level above 4 since shadows only appears if the graphics are set to 4+.

Interesting issue, can’t tell if this is a Bug or simply a Poorly made Roblox feature. I’m unable to re-create the issue though.

I am still experiencing this issue, I cannot provide a repro file but I know that it occurs in most games.

As for the repro steps :

  • Launch any Roblox game with future/shadowmap lighting.
  • Make sure the graphics are set above 6-8 so the detailed shadows are visible.
  • Pay attention to the shadows

I could confirm that this bug occurs on my Redmi Note 13 Pro 5G and Redmi 9T phones.

It does not occur on Iphone, Xbox One and PC afaik.

I currently have no clue on how exactly this happens, in some locations the shadows are broken, in others they aren’t. Therefore I can’t provide a helpful repro.
