KDE Plasma 5.9.4
KDE Framefork 5.32.0

My display has 4k resolution. I've set scale display x2 with KSettings, DPI = 192. All seems very good except desktop context menu and some buttons on dialog windows. Please see attached screenshot. Yellow box - scaled icons, red box - very small (unscaled) icons.
Is it a bug? Is there a way to scale these icons?

It's an older topic, but I thought I'd mention I'm seeing the same thing.
For me it's not just the desktop context menu, but also the Panel context menu and the launch indicator that have very small icons.
So far it seems like everything else scales correctly.
I did a quick search through the kde bugs but haven't yet found anything.
Anyone know if this is a but or just some misconfiguration?
I'm running Antergos with Plasma 5.11.3 on a Dell XPS 13 9360.

Thanks!

I'm not sure if it's related, but something else I've noticed is that the mouse cursor shrinks when hovering over the title bar, resize handler, text input, etc.
It seems to be about the same size as the smaller icons I'm seeing in the context menus.
