Summary: Currently, effects like Maximize, Slide Back have problems with setting WindowForceBlurRole. They store previous state of WindowForceBlurRole. This is wrong. Instead they should either ignore previous state of WindowForceBlur or refcount forced role. There's no need for refcounting right now. For example, if several effects force blur or background contrast, they are most likely in a conflict. Please notice that the Desktop Grid effect uses the Present Windows effect only to calculate transformations. Some other problems with the code that sets WindowForceBlurRole: * Maximize effect stores previous state of WindowForceBlurRole only for one window. It ignores the fact that there could be several active maximize animations; * Desktop Grid/Present Windows/Slide back don't clean after themselves. So, after using those effects for good amount of times, memory usage will bump. Test Plan: * Enabled blur for Konsole * Maximized Konsole * Activated Present Windows * Activated Desktop Grid * Raised another window(to trigger Slide Back) Reviewers: #kwin, fredrik Reviewed By: fredrik Subscribers: fredrik, kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D13479
