Description
Qt 6 seems to have some issue with rendering and is able to only draw couple of frames per second at most when using software rendering (QT_QUICK_BACKEND=software). One the same machine with Qt 5.15 and software rendering, the performance is significantly better.
Could be tested with quick nano browser example and software rendering. Load for example chrome://gpu to verify that it is software rendered and then try to scroll the page.
