+Subject: [PATCH] d-r: enable dirty-regions by default
+
+This enables the all-or-nothing mode, which means that we repaint the entire
+screen if there's a single dirty region.
+
+Also, nofliptimeout=0 is set to ensure that we never flip without rendering.
+
+With these combined, this should be universally safe (and within spec) for all
+gfx cards/drivers.
+
+The main possible side-effect is the slow-motion effect brought about on slower
+cpus that can't keep up at times and produce wild timestamps. With our improved
+decoding and caching, this is now quite rare.
