I recently switched to an X1 Carbon 4th gen with the nicer HIDPI display.
Sadly the rest of the desktop displays I plug into are still the old
density. I noticed recently in 5.7.4 that most Qt based applications will
do some notion of font DPI re-rendering when a window moves from one
display to another, which is a step in the right direction though I wish
there were some more exposed settings to specify which scaling factors for
each monitor independently.
Konsole has sadly stopped displaying the bitmap font Terminus properly on
the HIDPI display (the letters look squished and the kerning is horrible),
however when it pops onto my desktop display it looks fine. Using any other
normal truetype or openfont causes 1px wide horizontal and vertical lines
to get cut through the window displaying whatever is under it whenever
there's a bunch of text that scrolls by or if I highlight text.
Chrome (Chromium) thankfully respects my KDE global scale factor of 1.5,
however it absolutely doesn't care about this new behavior of rescaling
when the window moves between one display to another. It's been driving me
mad to the point where I'm now saving up for a new 4k monitor just so I
don't have to deal with this issue anymore.
Anyone have some good tricks dealing with these issues?
