Is this a variable fonts issue? Perhaps it should be moved to KDE or Qt
Would be good to try with F43 and F44
(In reply to Jens Petersen from comment #4) > Is this a variable fonts issue? > > Perhaps it should be moved to KDE or Qt Likely. However, The way the reporter pointed out didn't help for me (tested on f44). That said the root cause may be the same to https://bugzilla.redhat.com/show_bug.cgi?id=2179854 In fact, running dolphin with QT_NO_SYNTHESIZED_BOLD=1 do the trick. We should move this to Qt.
I was asked to drop my findings here, so here I am. I spun up a live Fedora 43 KDE VM on Distrosea and can confirm this issue is happening. ..although the VM is a bit out of date (6.17.1-300 kernel)
