Hi list,

driver version used: 2.99.917+git8674.25c9a2fcc-2.1
Xorg: 1.20.4


Is there a reason why the "intel" Xorg driver uses DRI2
by default instead of DRI3 ? If you want DRI3 you need to use
Option "DRI" "3".

Using DRI2 cause problems with compositors such as compton, in partocular
is causes scrolling in Firefox to stutter badly. Switching to DRI3 fixes the problem.

See the end of this compton issue for the discussion that led to finding this:

https://github.com/yshui/compton/issues/132

So shouldn't DRI3 be the default (it's the default when using the modesetting driver).

///

That's unrelated, but "man intel" mentions that the TearFree option is disabled by default while
I observed it was enabled by default on my system.
