This is a configuration issue with your graphics card/software. Common culprits are the GPU is too old and doesn't actually support the required opengl version, the GPU driver package is out of date and needs to be updated, or the GPU driver package unbundles opengl support and some support component for it needs to be installed/upgraded separately. If you can't get it to work that way, you may be able to use the "Fallback Graphics" mode in kicad to bypass hardware acceleration

You can try mesa3d software rendering opengl dll. I haven't tested it with kicad, but it made csxcad (from openEMS) work with remote desktop. For some reason, an ancient graphics card opengl driver refused to work in win10 when executed remotely. Of course it's better to find and fix the issue, maybe reinstalling graphics drivers would be enough.
p.s. I downloaded mesa3d here: https://fdossena.com/?p=mesa/index.frag
better late than never

I can’t help with Windows, but I may provide a hint on what to search for, if Georgy.Moshkin’s suggestion doesn’t work.

KiCad uses wxWidgets as its UI toolkit, and wxGLCanvas is used for 3D rendering. So the bug is somewhere on the line between wxGLCanvas and whatever it uses as its graphics backend on Windows, almost certainly out of KiCad’s influence.

On Linux-based systems Mesa may be set to use software rendering.(1) But I have no idea, if that works on Windows. OTOH Dossena’s version claims to already be using software rendering by default.


(1) GALLIUM_DRIVER=llvmpipe LIBGL_ALWAYS_SOFTWARE=true kicad — other software renderers maye be named in GALLIUM_DRIVER, but llvmpipe is both supposed to be faster and it “just works” for me.
People imagine AI as T1000. What we got so far is glorified T9.
