KDE panel animation freeze when using PLASMA_USE_QT_SCALING


when I do a fresh install of kde, and set my scaling to 250% some widgets don’t scale properly ,for example menu icons in Desktop right click or panel itself don’t scale and are very small. in this situation, panel animations (auto hide option) works properly. when I set PLASMA_USE_QT_SCALING=1 in my bash profile, 99% of scaling issues solve but another problem rises! desktop animations like panel auto hide or latte dock become completely unresponsive.
so now I stick to default panel settings and I cannot use latte. Do you know the solution?

PS: I use nvidia drivers and did not check the open source ones
