[systemsettings] [Bug 431197] Sub-pixel anti-aliasing is not being applied
https://bugs.kde.org/show_bug.cgi?id=431197 --- Comment #31 from Nate Graham --- I strongly suspect that this is related to the fontconfig shipped by the distro, which would explain why it could be working in Kubuntu but not Neon. -- You are receiving this mail because: You are watching all bug changes.

I've attached the following screenshots: Test 1 - Default Slight Hinting with RGB (2021-04-19).png Test 2 - Full Changed to Full Hinting with RGB (2021-04-19).png In the first test, using default out-of-the box settings, you can see the colored fringes around the text. The settings were Slight Hinting with RGB. In the second test, using updated settings with, you can see the also colored fringes around the text. Notice that the fringes have different darker colors around some of the characters. The settings were Full Hinting with RGB. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431197 --- Comment #22 from nyanpasu64 --- Created attachment 135435 --> https://bugs.kde.org/attachment.cgi?id=135435=edit Output of "fc-match -v" (unchanged under None vs. RGB) > Qt apps running on Plasma have their text rendered using gray-scale (tested > with Dolphin and VLC), while GTK3 apps (also running on Plasma) have their > text rendered with RGB anti-aliasing (tested with Simple-scan). I observed the same bug, with the added property that Firefox (and most likely GTK3 apps as well) doesn't turn on LCD filtering, resulting in prominent color fringes on vertical text edges. If I set KDE to grayscale antialiasing, both Qt and GTK apps (including Firefox) use grayscale properly. Clicking Apply in KDE's font settings writes to the file "~/.config/fontconfig/fonts.conf". Bafflingly, the file written is identical whether you pick None (grayscale) or RGB in the KDE settings. So I don't know how GTK even picks up a change in subpixel rendering. The output of "fc-match -v" is identical whether run from gnome-terminal or alacritty (didn't test Konsole), whether KDE is set to None or RGB (which changes the appearance of gnome-terminal). So I don't know why GNOME app rendering (including gnome-terminal) changes when I change KDE settings, when the fontconfig rules aren't changed. I've encountered this issue on Arch Linux (unsure which Plasma version). I "fixed" the issue by adding a system-wide (or user-wide) fontconfig XML rule to manually set rgba to rgb and lcdfilter to lcddefault (https://wiki.archlinux.org/index.php/font_configuration#Pixel_alignment). Recently I switched to Garuda Linux (an Arch-based ricer distro with new and exciting bugs) and Plasma 5.20.5, and the bug is back. I suspect https://bugs.kde.org/show_bug.cgi?id=416140 may be related to this bug. It describes similar symptoms, but was reported in 2020 January (months before I encountered a similar issue). And that bug report also has some commonalities with my experience written above: > Even if sub-pixel rendering is enabled, there's no trace of this setting in > ~/.config/fontconfig/fonts.conf > If i create a symlink in /etc/fonts/conf.d to > /etc/fonts/conf.avail/10-sub-pixel-rgb.conf, fonts improve a lot. -- You are receiving this mail because: You are watching all bug changes.

For me, font rendering is one of the most important visual properties of an OS. I believe this is also true for many others who spend most of their lives reading and writing a text on the computer. I wonder why the distro was released with a bug like this. Is it possible that none of the NEON testers noticed that? -- You are receiving this mail because: You are watching all bug changes.
