qBittorrent was already quite ugly, but this is just awful: https://github.com/qbittorrent/qBittorrent/issues/18078#issu... — why that bright blue on top of white? If you really want to make it blue, at least retain a decent contrast. And let's not even start with those icons... The shapes could work, albeit they are quite unrefined, but the garish colours do not convey any information nor show any artistic consistency.
(cue the "it's open-source, if you don't like it fork it, but dare not criticize us because it's rude" comment)
I am fine with people not being good at design, but the worst designers are convinced they are decent enough. It's like that law that eludes me right now, that people bad at something often overestimate their abilities and are blind to their shortcomings.
