Description Nate Graham 2018-01-29 14:48:02 UTC
This comes up a lot in online reviews of Plasma and internet forum chatter.

Currently, there are three settings for Anti-Aliasing:
- Enabled
- Disabled
- System Settings

The default is "System Settings. This is sub-optimal for multiple reasons:
1. It's not clear to a user what "System Settings" means
2. This setting respects the system's existing settings, but those settings are bad in 100% of distros that I have tested

To ensure a better user experience, I recommend that we change the default setting to "Enabled", and use slight RGB font hinting on the configure dialog. These settings are optimal for 100% of computers that I have used or supervised other people setting up, and at least one major Linux distro reviewer found that they were best for him, too: http://www.ocsmag.com/2018/01/27/plasma-5-12-long-term-sweetness/

Distros can still override this if they want, but using better defaults will prevent most of them from having to, I expect.

And lest you be tempted to say "RESOLVED DOWNSTREAM, distros should do this", well, a lot of distros don't really seem to care about it or have the manpower to do it. See for example https://phabricator.kde.org/T7618

We have a great opportunity to improve the appearance of fonts for nearly all KDE Plasma users by changing the default setting.

+1 from me! Looks good on a modern laptop.
Comment 3 Nate Graham 2019-05-21 15:31:21 UTC
Apparently we are setting things incorrectly in startkde. See Bug 407754.

This bug is not duplicate of the referenced bug, whatever default is set by startkde needs to be set by krdb, somewhere else, and those needs to be changed.

Re-opening.

Make slight/rgb the default option

Medium hinting and None subpixel rendering was default options added
when we used Oxygen fonts, however freetype recommends slight hinting as
seen in this blog post from 2015 [1].

Also RGB hinting is most-recommended over the None. See linked bug
report as well.

Set defaults for anti-aliasing using the krdb

We used to write a configuration for the anti-aliasing using the
startkde script, startkde script would write to kdeglobals and then read
this configuration in the krdb.

This had un-intended side-effect of $XDG_CONFIG_DIRS/kdeglobals settings
or settings set by ~/.config/fontconfig/fonts.conf not being used.

D21335 fixes this by not writing to kdeglobals anymore, this transfers
the defaults used by startkde here.

Git commit 1af4680ea8464e0f6f444c103d49887fe219ee27 by Bhushan Shah.

Don't write a anti-aliasing settings from startkde

Summary:
Writing a config files in $HOME at start-up is wrong way of setting
defaults, If defaults needs to be set, they should be set by krdb
instead of the startkde.

Another side-effect of writing config file is that this breaks the
distribution/vendor configuration, who might want to configure this
value by shipping kdeglobals in either /etc/xdg or $XDG_CONFIG_DIRS.
