Comment # 2 on bug 1221116 from Breinbauer

For me, the qt5 backend is *very* laggy (resizing an image with the mouse takes
several seconds, scrolling through a document is really awkward). The gtk
backend works much better. I found some "rumors" that the qt5 backend is the
culprit, therefore I would like to have qt6 backend enabled.

Also, now that Plasma 6 is out, qt6 becoming the default is to be expected?


Here is the meta bug for qt6 plugin:
