Description:

Hello. I recently switched computers, and therefore now use the xf86-video-intel driver. No complaints, seems to work really well. Problem is, scrolling a page in Firefox caused heavy tearing on my new laptop, which should fast and shiny. After digging around, i discovered that the driver has a "TearFree" option that i had to enable, which solved my problems! It just strikes me as really weird, that an option which to me seems, for all intents and purposes, equivalent to a "Don'tKeepCrashingAllTheTime", should be disabled by default.

That's all. I thought it'd be reasonable to enable that by default. I've done a minor amount of searching, and discovered that there is a build flag to enable it by default, see here: <http://lists.freedesktop.org/archives/xorg-commit/2014-June/036677.html> -- perhaps that would make sense, if only for Arch?

If not, what is the rationale behind this decision?

Thank you for your great work!

@Pyroh - The bug report you referenced has some compelling reasons why *not* to enable it by default as made by the developer himself, https://bugs.freedesktop.org/show_bug.cgi?id=37686#c123
