Very similar bug in my case on mac os Catalina (with openGL 3.3 support - geforce 9600M GT graphics card, legacy hardware in other words). Although instead of the red color, the white hue is converted to cyan in the scene view (see attached picture). So far I have found some similar topics as in here and here , but none was helpful in my case.
Built-in, URP with (2D Data) renderer projects are fine. The moment I add the URP (Universal renderer) asset the issue comes up only in scene view (shaded mode) and urp material preview. It seams to be a malfunction between certain graphics drivers (not sure if it occurs only in old hardware) and the way the scene and material preview cameras are compiling the URP shaders. Seemingly, the result is that the white color output has no zero rgb values.
Two sidenotes:
- The newest version I don’t have the issue is unity version 2021.3.28. As a matter of fact I had graphics issues again in URP projects and in the scene view in that version, but they were resolved the moment I switched to lower quality settings.
- All of my testing was done in several 2022+ versions, with new projects, and the default settings except of one: I have selected ISPC (legacy) in the BC7 Compressor Editor settings, because otherwise Unity crashes when URP assets are imported. (see here )
