Description

When you set e.g. 120% UI scale, the fonts all end up very blurry and almost unreadable.

Instead of rasterizing the fonts and using bilinear scaling on the results, you should update the font size to match the UI scale instead.

I would clarify that the fonts look terrible at all UI scales, not only at 120%. See this screenshot: the mission time and surface speedometer look like they've been rasterized and resized, while "Reaction Wheels" in the pod menu is for some reason a different font size than everything else.

There's something going on with the font anti-aliasing under Linux, but it's not quite so straightforward as you suggest. Some of the fonts are antialiased at different UI scale settings.

I captured the same dialog using 4 different UI scale settings (editing settings.cfg to get >120%). Mainly it seems the "squeezed" fonts for the texts "MonoPropellant" and "CarbonDioxide" look out of place. Especially "MonoPropellant" is antialiased too strongly at 100%/120% but not at all at 150% which also looks odd. At 200% everything looks fine, so it's not just an obvious scaling issue.

I don't know how Unity5 treats fonts, but maybe it has to do with some graphics settings? I'm using Kubuntu 14.04.4 LTS with NVidia GTX 970 (with nvidia-352 drivers if it matters). However changing the Kubuntu font settings seems to have no effect on Unity5, so I don't know which settings to look at instead.

(Note that I've enabled TAC-LS and KIS to have more lines in the dialog to compare; I'm quite sure that they wouldn't affect font rendering.)

Maybe one fix would be to make the windows slightly wider so that fewer text items needs font squeezing.

There are still some things odd about the 200% screenshot, incidentally. For example look at the N (magnified, attached) - the line thickness seems uneven in places like this. Even if it's unscaled, it's almost as if the subpixel alignment is wrong.

The 100% screenshot on the other hand is perfectly crisp, pixel-perfect rendering (with the obvious exceptions as noted).

This bug has not been fixed in 1.1.3; behaviour is exactly the same as in initial bug report AFAICT.

The new text rendering method should have improved the readability of all text in KSP 1.2
