It's far easier for Microsoft to test on different devices than it's for Linux volunteers. I have seen countless times where KDE and Gnome developers couldn't reproduce the issues mentioned because they didn't have to the hardware on which the problem was reported.

This doesn't mean Windows doesn't have hardware dependent bugs of course.

While it is not out of the question, Microsoft’s employees are disincentivized from testing on various hardware, as spending time to do testing does not contribute to their performance evaluations.
