--- Comment #14 from David Edmundson <k...@davidedmundson.co.uk> --- What do you mean exactly by "notifications are drawing at 200fps"? and yes, it should be vsynced, there's code to do it (in Qt) There's a nice line in the Qt documentation on that: >Note: The threaded and windows render loops rely on the OpenGL implementation >for throttling by requesting a swap interval of 1. Some graphics drivers allow >users to override this setting and turn it off, ignoring Qt's request. Without >blocking in the swap buffers operation (or elsewhere), the render loop will >run animations too fast and spin the CPU at 100%. If a system is known to be >unable to provide vsync-based throttling, use the basic render loop instead by >setting QSG_RENDER_LOOP=basic in the environment. Though if you're on intel on X, you should be running on basic anyway. Can you run QSG_INFO=1 plasmashell but I also don't want to get distracted from the first thing we were actually doing: there are multiple kwindowsystem.cpp files, I meant ./platforms/xcb/kwindowsystem.cpp -- You are receiving this mail because: You are watching all bug changes.
