This is the second thread on this I've seen. I can't say for sure whether the first one was, but it must have been either one of the kde lists (perhaps even this one), or on the plasma development list, which I follow because I run live-git kde-frameworks/plasma/apps and which gets CCed from plasma bugs filed on kde's bugzilla, plus the plasma-related phabricator patch postings up for review before they get merged to the various git repos, and it might actually have been a bug thread or phabricator bug patch thread I'm remembering. Actually, given that I remember clicking links to images illustrating the problem in the thread, it's very likely I /was/ reading it on the plasma- devel list, and thus that it was either a bug or a phabricator issue. Meanwhile, I should say that I have NOT noticed the bug myself, in live- git plasma/frameworks as I said, but that's likely explained by the below... Apparently the bug affects only certain window decorations, and the one I'm running, BlackSquare from the kde store (get new window decorations in the window decorations kcm, aka kcontrol module, aka kde system settings module), isn't affected, because it's an aurora-based theme, and according to the earlier thread, aurora-based themes aren't affected. (I'm no windeco expert, and don't properly know to my own satisfaction what aurora is or what makes it distinct enough from the other windeco alternatives to not suffer from this bug (doing some research on it has been on my low-priority to-do list for some time now, but being low priority, it may remain there forever...), but based on browsing kdelook and the kde store for years, it's apparently a quite popular windeco "engine", that makes creating your own windecos reasonably easy, so much so that there's a whole bunch of aurora-based windecos created by various people, up on the kdestore, and kdelook, before that.) On the bug/phabricator/whatever, the issue was somewhat different, however. There, the problem was not font size, but the fact that a user's /bold/ settings weren't being honored appropriately. As pointed out by the user and as illustrated in the images, while the "bold" setting did indeed make the font display slightly heavier, it was an "emulated" (original user's word) bold, NOT the actual font in bold face as shown in a few other images, from other elements of the UI. IIRC font smoothing was also affected, tho it's possible I'm mixing that up from a separate bug, or possibly a different report of the same one, I'm not sure. In any case, try choosing a different windeco (kde system settings, application style, window decorations). Plastik shouldn't be affected as I /believe/ it's aurora-based. Breeze is I believe the default and affected. Oxygen is the old kde/plasma4 default, and I'm not sure whether it's affected or not. Those are the three choices that normally ship with plasma. As mentioned, others can be downloaded, and I'm using the aurora-based BlackSquare as downloaded from the store, here, which doesn't seem to be affected. I'll also see if I can find that other thread and post a link to it. -- Duncan - List replies preferred. No HTML msgs.
