From d4e937a6280f34bc1cce8c8cea3806a741312fbc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?B=C5=82a=C5=BCej=20Szczygie=C5=82?= Date: Tue, 25 Sep 2018 18:45:10 +0200 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.
