From the bug report the fix did not went into the stable branch for good reason. It causes another regression. I'm for holding it back until 1.18.

I still needed to apply the scaling patch to fix the mouse boundaries on xorg-server-1.18.0-3

"As a result of our testing, I have to state that, with the patch, the pointer is not constrained properly on the right side if one applies keystone correction. That's with xorg-server 1.16.1, will now retest with the latest git.

Retested with the latest git. The patch indeed breaks constraining the mouse on the right side when keystone correction is active. However, the whole "keystone correction" feature is already so horribly broken that I'd just propose to drop it.

The breakage is that, if you click something, the click will not go into a point that you intended to click. I.e. you can't even undo the damage using the xkeystone GUI."

If you find it useful to patch you local X go on. As long as upstream won't fix it in a proper way I won't apply it.
