Hello,

I have a hidpi display (2560 x 1440) on my lenovo x1 carbon, to scale Qt and Gtk application one must set the following environment variables:

Code:

QT_AUTO_SCREEN_SCALE_FACTOR=1
GDK_SCALE=2

(As explained in many articles like this one)

For Gtk3 application it works well, for Qt it looks like fonts are rendered incorrectly as you can see on this picture:

Note : on other distributions it works fine, I think I should miss a use flag or something like that.

The output of emerge --info

Do you have any ideas?

Adjusting Xft.dpi to 192 in .Xdefaults fixes the problem.
