Since Unity Technologies asked us to post our suggestions to the forum, here is my first feedback…
If I run our game on Android, it outputs:
WARNING: RGBA Compressed BC7 sRGB format is not supported, decompressing texture
WARNING: RGB Compressed DXT1 UNorm format is not supported, decompressing texture
It would be enormously helpful if the warning message contains the texture name.
Same problem, I’m a bit clueless 
RGBA Compressed BC7 UNorm format is not supported, decompressing texture
RGB Compressed BC6H UFloat format is not supported, decompressing texture
RGBA Compressed BC7 sRGB format is not supported, decompressing texture
RGB Compressed BC6H UFloat format is not supported, decompressing texture
I’m using LWRP. building windows 64 bits
I can surely manually scroll within all my textures, but still. That could be a very nice quality of life improvement.
Also RGB(A) Compressed BC7 isn’t supposed to be supported on windows DX11 ? (Unity - Manual: Recommended, default, and supported texture formats, by platform)
By the way, with LWRP/PpV2, we always get those warnings. Can’t they be directly stripped off?

Could you file a bug report? I did try to fix this issue a few weeks ago but it seems that the name of the texture is not available at that part of code. If we had a bug report it would be easier to work, I didnt have a reproduction at the time.
I believe this is a known issue, which should be fixed in some Unity versions already:
https://issuetracker.unity3d.com/issues/unity-outputs-a-warning-in-a-windows-64bit-standalone-player-when-using-built-in-shaders
If you’re able to reproduce the issue with a more recent Unity version, it’s probably a good idea to submit a bug-report for it as well.
I’ll do a new bug report for that unsupported shader. But I’m also very much concerned about the whole:
RGB(A) Compressed BC7, RGB Compressed BC6H etc…
Aren’t supposed to be supported on windows ? (Unity - Manual: Recommended, default, and supported texture formats, by platform)
Isn’t that two very different issues ?
Yes.
WARNING: RGBA Compressed BC7 sRGB format isnot supported, decompressing texture
and
WARNING: Shader Unsupported: 'Hidden/PostProcessing/DepthOfField' - Pass 'CoC Temporal Filter' has no vertex shader
… are different issues.
The shader problem has nothing to do with my initial feedback that they please improve the texture compression warning.

I work on an older Macbook Pro and use ASTC for my mobile game, so I get spammed with “RGBA Compressed ASTC4X4 sRGB format is not supported, decompressing texture” often.
It would be SO helpful to know which texture it is talking about!
Could you file a bug report, please? Its the best way to get eyes on this.
@karl_jones We have filed a bug report. As it is now, it is impossible to locate the textures and fix the problem in a real-world / larger project with hundreds of textures.
Also, we have high quality compression enabled on most of our textures but there are only 20-30 warnings in the log file. Shouldn’t BC7 be supported on macOS? Or does the problem only affect some specific configurations such as “non POT with alpha” or something similar?
Here are the warnings that we’re getting:
15: [Unity] WARNING: RGBA Compressed BC7 UNorm format is not supported, decompressing texture
16: [Unity] WARNING: RGB Compressed BC6H UFloat format is not supported, decompressing texture
We’re on Unity 2020.2.0f1.
I guess this is the bug-report that was submitted:
https://issuetracker.unity3d.com/issues/warning-for-the-unsupported-texture-doesnt-mention-the-textures-name-when-unsupported-compression-format-is-used
@karl_jones we have these warnings on UCB (lot’s of them) - regular windows x64 build
I guess you can get access to our project on UCB so you can dig in to see what’s going on? Let me know if I can help.
Could it be that it’s lightbake textures?
Im not aware of any way to access UCB, it’s not something I have done before.
You would need to file a bug report.
Did you find reason? we have same issue to
I’m getting this in Cloud Build too. How does a texture “become” UNORM? What setting makes it “Unorm” vs not? I think that might be the key because otherwise building for Windows 64 bit standalone shouldn’t give this error:
RGBA Compressed BC7 UNorm format is not supported
