I can't speak from experience with their GPUs on Linux, but I know on Windows most of their problems stem from supporting pre-DX12 Direct3D titles. Nvidia and AMD have spent many years polishing up their Direct3D support and putting in driver-side hacks that paper over badly programmed Direct3D games.
These are obviously Windows-specific issues that don't come up at all in Linux, where all that Direct3D headache is taken care of by DXVK. Amusingly a big part of Intel's efforts to improve D3D performance on Windows has been to use DXVK for many titles.
