It's interesting to hear this. I have not tried very much, I admit.

People don't talk enough about OpenGL and the need for working 3D
drivers. A bunch of "modern" desktops are based on OpenGL rendering
and _need_ 3D to work. Sometimes if it's not there, they will work via
software rendering, but performance is poor this way. GNOME and its
fork Cinnamon need it. As Elementary/Pantheon is also a GNOME 3 fork,
I'd guess the same applies there too.

KDE officially doesn't, and you can turn it off, but in my testing
turning it on or off doesn't actually help and in testing using OpenGL
passthrough in VirtualBox, neither way worked and there was serious
display corruption rendering it unusable. I suspect the enable/disable
functionality has not been properly tested and is or was buggy.

Unity needed it but by modern standards is quite lightweight and works
OK with software rendering. This is why there are problems: modern
CPUs are so fast, software OpenGL is good enough and people don't
notice the problems.

MATE can use it but doesn't need it; it's a fork of GNOME 2 which
predates this stuff.

XFCE and LXDE/LXQt don't need or use it directly at all, and I *think*
have it off by default (depending on distro, obviously) but you can
enable an add-on compositor for transparency effects and shadows if
you want.
