I have to imagine software incompatibilities appear semi-frequently. Running Windows 10 on that can’t be a good experience.
actual issues are rare actually, it pretty much just works as long as the hardware supports the features the application requires. if it doesn't it will likely throw an error and not run.
you are right in that its an awful experience though, its usable but you have to debloat it and even then its slow. can't watch hd video either.
