Your idea

Qt6 removed opengl32sw.dll from the distribution. We need to reconsider how to best support OpenGL going forward.

OpenGL is well-supported on macOS and Linux. Windows is the challenge with older machines that have Intel Graphics and buggy / out-of-date drivers.

Perhaps we can consider recommending Mesa3D for the customers who run into issues? Here is what another OpenGL application recommends.

One of our customers used Mesa3D to support ancient (circa 2010) hardware with Windows 10. Here was the process:

• Go to https://github.com/pal1000/mesa-dist-win/releases
  • download mesa3d-24.3.4-release-msvc.7z (for windows 10)
• with file explorer (assuming 7z installed) ...
  • extract the zip.
  • copy opengl32.dll, libglapi.dll, and libgallium_wgl.dll​ files.
  • and paste into C:\Program Files\Joulescope
• from cmd prompt in any folder ...
  • setx GALLIUM_DRIVER llvmpipe

Does your idea concern a specific OS?
