By profiling qTox using perf I discovered, that NotificationIcon::updateGradient takes significant amount of CPU time even though qTox is idle and no one is typing. This commit fixes: 1) correctly determine visibility of NotificationIcon 2) only invalidate boundingRect in fixed intervals 3) apply the same fixes to Spinner since it has the same problem
