Better than X but still not perfect. If you have neat monitors where the difference in pixel dpi is simply an integer multiple (1×, 2×, etc) it's really good, no issues at all. If you need fractional diff in pixel dpi (e.g. you want one screen at 1× and the other at 1.5×) it can kind of work, but dodgy - the 1.5× screen will have its windows rendered at 2× then downscaled, so won't be pixel crisp (and the unnecessary 2× render can push limits on old integrated graphics cards) If you need diff in text dpi, e.g. like setting Xrdb.dpi or gnome's Scaling Factor, then you're up shit creek (but with X11 to keep you company)
