chrome vs falkon on a 2x scale screen

High DPI handled poorly on Windows. On a high-resolution (24" 4k, 200% scale) and low-resolution (27" 1440p, 100% scale), when open on the high res monitor:
- address bar and other toolbars are clipped, half sized
- click areas are off: one needs to click cca 20px below the address bar to get the address bar activated. Similar issues with other toolbars, and event to the web area
- web area doesn't scale (sits on 1x scale regardless to which monitor it is on)
- when moved to the low DPI screen, icons get very pixelated and look oversized

The poor scaling occurs on Kubuntu 18 too. The font is so small on my monitor that I can't even read the page.
Comment 2 Pavel 2019-06-15 08:26:10 UTC
Same thing in Gentoo.
Please provide a setting for scaling, like layout.css.devPixelsPerPx in Firefox.
Comment 3 David Rosca 2019-06-15 09:31:23 UTC
You can use QT_SCALE_FACTOR environment variable for scaling.

It would enlarge the UI as well. 
UI is displayed correctly now, only the webpage is too small.
Comment 5 David Rosca 2019-06-15 10:55:02 UTC
Well, you suggested layout.css.devPixelsPerPx from Firefox which does also affect UI.
If you only want to scale webpages, you can just use zoom.
Comment 6 Pavel 2019-06-15 10:59:39 UTC
But zoom will not apply to new tabs...
Comment 7 David Rosca 2019-06-15 11:06:39 UTC
There is default zoom option in preferences.
