+Subject: xcb: Don't get initial screen rotation
+
+"xcb_randr_get_screen_info" can be slow and in some configurations can
+cause short mouse cursor freezes (which will happen on Qt application
+startup).
+
+Initial screen rotation was used only to not handle possible redundant
+screen change event.
