Error messages on AMD graphics

[Merodi]

I'm using an AMD Radeon R9 Fury Nano graphics card and build panda 3d with win10 and vs2015.

Panda3d and RenderPipeline sources are cloned from github.

my build command is:
thirdparty\win-python3.6-x64\python.exe makepanda\makepanda.py --everything --threads 5 --msvc-version=14 --windows-sdk=10 --no-dx9 --no-tinydisplay --no-nvidiacg --no-fmodex --no-ode --no-physx --no-pandaphysics --no-maya6 --no-maya65 --no-maya7 --no-maya8 --no-maya85 --no-maya2008 --no-maya2009 --no-maya2010 --no-maya2011 --no-maya2012 --no-maya2013 --no-maya20135 --no-maya2014 --no-maya2015 --no-maya2016 --no-maya20165 --no-maya2017 --no-max6 --no-max7 --no-max8 --no-max9 --no-max2009 --no-max2010 --no-max2011 --no-max2012 --no-max2013 --no-max2014 --no-deploytools

I changed vc_version=Visual Studio 14 2015 in rpcore/native/config.ini and build RenderPipeline.

All build successed, but almost every sample from RenderPipeline-Samples-master shows:

[!] Panda3D :linmath(warning): Tried to invert singular LMatrix4.

[!!!] Panda3D :display(error): Shader input IESDatasetTex is not present.

this errors do not appear when i use NVIDIA GT 730 card.

any way to solve it?
Thanks!

I also have some problems with my Graphics card AMD Radeon RX6800. I have pulled the latest master branch as described in the getting started guide. However when I try to run any examples such as the material demo I am getting a lot of shader errors on startup. I am running this under Ubuntu 20.04LTS with the proprietary graphics drivers.

The output I get when starting an example (e.g material demo) is the following:

The example runs but I get some really bad flickering and the FPS is also not optimal (below 30 FPS). If anyone has any idea what to do in this situation, it would be greatly appreciated.

I just noticed that this error I reported is actually related to: #105.
Therefore the comment above can be ignored.
