--- Comment #8 from grouchomarx...@gmail.com --- It seems that my bug 409035 concerns QtQuick apps and the fact that they are using Opengl to render everything. They make my Ironlake GPU hit 100% very easily. If I force the software backend, the desktop is fluid again. It is very likely that my GPU is too weak. But it may also come from the apps, QtQuick, or the driver. I am not sure how to debug this. In the meantime, I am using QT_QUICK_BACKEND=software as a workaround. -- You are receiving this mail because: You are watching all bug changes.
