please look at the screenshot, I'm using a 4k screen with hidpi (dpi scale=200%) the font on the toolbar is still small, it kill's my eyes.

It seems the ui size of HiDPI is set to about 175% of normal dpi.

How about a slider of UI size? so I can use real 200% scale of UI?

You can test it by scale the screenshot to 50%, and see by yourself, isn't the toolbar font too small for you?

It's not a mistake in gentoo, seems gentoo must install this file into /usr/share/X11/rgb.txt

BTW, I think there must be some api to get the rgb path in xorg.

And, modular xorg means I do NOT need to compile all components for xorg running? right? then not install all, the app should do the change.

just my opinion

And, if xorg need rgb.txt, there is another way to get the content of this file right?

Yes, the rgb.txt thing is a gentoo issue.

the rgb.txt path for gentoo is changed to /usr/share/X11/rgb.txt,

and also, make link to this file in $HFS does not help any ..
