Description Stephan Rütten 2018-11-08 07:45:24 UTC 
SUMMARY

When I change the anti-aliasing settings from 'Vendor Default' to anything else anti-aliasing is disabled and cannot be enabled again without deleting ~/.config/fontconfig/fonts.conf.

STEPS TO REPRODUCE
1. Change the anti-aliasing settings from 'Vendor Default' to anything else.
2. Log out and log in again.
3. Enjoy ugly fonts.

OBSERVED RESULT

Resetting to the defaults with the 'Defaults' button is only cosmetic, it doesn't reset to 'Vendor Default' (in which state anti-aliasing was enabled).
Setting anti-aliasing in any way doesn't work, logging out and in again or even rebooting doesn't help.

EXPECTED RESULT

I should be able to set anti-aliasing settings and reset it to the default.

Comment 2 Patrick Silva 2019-02-24 17:07:36 UTC 
Forget. After relogin, fonts look horrible and can not be fixed via Fonts kcm.
Comment 3 Bhushan Shah 2019-06-12 07:12:08 UTC 
Vendor Default option has been removed from Plasma git master (to be released as Plasma 5.17). If possible can you check with git master or for example Neon dev unstable edition and see if you can still reproduce this? or is this bug even valid?
Comment 4 Patrick Silva 2019-06-14 22:10:01 UTC 
I tested all options available in "Sub-pixel rendering" dropdown,
the fonts looked good after every relogin. Tested on Wayland if it matters.

Cannot reproduce with 5.17. Looks like you fixed it! \o/
