--- Comment #6 from Anton <anton.b...@gmail.com> --- Ok, I think I managed to find the root of the problem It is a documented problem: https://doc.qt.io/qt-5/qtquick-visualcanvas-scenegraph.html "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" I have managed to fix it by running: QSG_RENDER_LOOP=basic plasmashell --replace -- You are receiving this mail because: You are watching all bug changes.
