There's no general thread, so I'll start one.
Many of us have problems with Chromium-engine browsers and newer Firefox, as they add their own dithering solution (easy to see with ditherig on - no banding on images), so I think it's a good idea to look for alternatives.
Here how it is for me:
- Perfect browser: Pale Moon (newest version), old Edge (on 1803)
- Bearable strain: new chromium-based Edge (using 84.0.516.1, there is clear dithering, but is does not bother me much)
- Not good: Firefox Quantum
- Terrible: Chrome, QT-based browsers
