Description Stephan Sokolow 2007-02-01 19:11:12 UTC
Version:           1.0 (using KDE KDE 3.5.5)
Installed from:    Compiled From Sources
Compiler:          Target: i686-pc-linux-gnu
OS:                Linux (i686) release 2.6.17-gentoo-r4-20060825

Lines in Filelight aren't anti-aliased. As such, lines drawn at certain angles will look jagged even on an eye-strainingly blurry CRT. On my new LCDs, it's horrifying.

Can only be fixed when ported to Qt4.

This is also reproducible with the latest Flatpak: https://github.com/flathub/org.kde.filelight/pull/34
Comment 8 Timothée Ravier 2024-04-15 17:47:52 UTC
It's a regression as it used to work on the KF5 based version.

Issue was fixed for me in the recent updates

Still repro on Plasma 6.0.4
Comment 12 Timothée Ravier 2024-04-23 12:45:03 UTC
This looks indeed fixed with 6.7 (or with the latest kirigami-addons).
