UHD 4K Screen and GTK3

Hello,
I have a fresh install of Arch Linux with KDE Plasma Desktop. I use 4K UHD Samsung screen with 3840x2160 resolution. Qt and GTK2 apps are scaled nicely to 2x ratio, but GTK3 apps are 1x ratio. And it makes apps which use GTK3 look small and tiny in my screen. For example gtk-demo runs nicely with scaled UI elements, and gtk3-demo runs tiny elements. So my Firefox web browser renders everything very tiny on the screen. How do I adjust GTK3 settings? Do I need to install some additional software or is it possible just to edit some config files?

I do not have a hidpi monitor but you won't have useful answers unless you give more details of what you have already done. What have tried exactly? Have you read the wiki? (for example I see export GDK_SCALE=2). What DE do you use?  GTK3 should normally work.

Re: UHD 4K Screen and GTK3

As I wrote, I use KDE Plasma Desktop. All I did is tried that export GDK_SCALE=2 which you mentioned. It did not help. I did not try anything else. Yes, I read wiki: https://wiki.archlinux.org/index.php/HiDPI this page, but nothing applies, only that exporting scale value, which did not help. GTK2 ant Qt works normally, scaling as it should, just problem with GTK3... Maybe there is somekind configuration utility for GTK3?
