      Description

      The "Flip compressed texture" is ignored and he KTX textures are not displayed properly if we are using the "Use ktx textures if available" option.

       

      • If the KTX texture is applied explicitly to the object the texture is displayed as it should be.
      • If the texture is applied as PNG and then the runtime uses the KTX the flipping of the texture is ignored
      • On custom shaders the flipping of the texture is ignored
      • Tested on VM/Linux and Target hardware
      • Used ASTC or ETC2 compression for the test
