davidedmundson added a comment. Since the introduction of this patch we have seen a deadlock when QtQuick calls glXSwapBuffers: https://bugs.kde.org/show_bug.cgi?id=406180 QtQuick is used a separate GL context with a different render path, often in a different thread to kwin's main rendering. It's used in various tab switchers and the frame rate is not directly tied to kwin's render updates (*though this is something I did want to fix...maybe it would be a solution?). The introduction of the environment seems to have had an adverse effect on this separate codepath. This freeze is not universal, unfortunately. Can you clarify what multiple glXSwapBuffers blocks until?
