[SOLVED] tiny menu font for QT app on 4K #32 after install plasma

Hi, I use GNOME + wayland.  I installed plasma 6 a few days ago, when that I re-entered GNOME, the display scale 100%,  font scale factor set to 2.0,
But all the QT app menu fonts became very very small, How to fix that? Is there a font setting program for qt applications only?

because all GTK app display good in GNOME, at the same time, GTK + QT both display very well on plasma 6, it just not work for qt display in GNOME.

thanks.

# ~/.profile
