Обновился до Fedora 29. Возникает подозрение, что десктоп не через GPU рендрится, а процессором. Такой подёргивание, подтормаживания странные появились. Gnome. Сессия wayland. Раньше всё нормально было. admgpu загружен.
Куда теперь смотреть надо, чтобы понять, что он аппаратно рендрит? А то может через llvmpipe?
P.S. выхлоп glxinfo64:
