Additional SRU-formatted information for review: [ Impact ]
Dolphin 4:23.08.5-0ubuntu4 on Ubuntu 24.04 LTS can retain stale item- view font/style metrics after changing zoom or view font settings. On KDE Plasma systems using 200% scaling, this can leave Details view item text oversized and overlapping after zooming in and back out, making file lists difficult to read and use. [ Test Plan ] 1. On Ubuntu Noble with Dolphin 4:23.08.5-0ubuntu4, use KDE Plasma with 200% scaling. 2. Open Dolphin in Details view. 3. Zoom in and then zoom back out. 4. Observe that item text can remain oversized and overlap rows. 5. Install a Dolphin package with upstream commit 8010ae0286fb30d51fff150703096f7ebe6172a9 backported. 6. Repeat the same zoom in/out sequence. 7. Item text should return to the expected size and no longer overlap. 8. Also verify normal Dolphin browsing in Details view still works with default/system fonts. [ Where problems could occur ] The change is limited to DolphinItemListView::updateFont(), specifically synchronizing KItemListStyleOption.font and fontMetrics for both system- font and custom-font modes. The main regression risk is in Dolphin item text rendering: users with custom per-view fonts, system font changes, or non-default scaling could see unexpected font sizing or spacing. Testing should therefore cover Details view zoom changes, default/system font mode, and custom view-font behavior if available. [ Other Info ] The fix is an upstream KDE commit associated with KDE Bug 511604: https://bugs.kde.org/show_bug.cgi?id=511604 Upstream commit: https://invent.kde.org/system/dolphin/-/commit/8010ae0286fb30d51fff150703096f7ebe6172a9 A packaging merge proposal for Noble is available here: https://code.launchpad.net/~lukavodopivec/kubuntu-packaging/+git/dolphin/+merge/506906 The current development packaging branch is already on newer Dolphin 26.04.x, so this backport is intended specifically for Noble's 23.08.5 package. ** Bug watch added: KDE Bug Tracking System #511604 https://bugs.kde.org/show_bug.cgi?id=511604 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2157573 Title: Dolphin keeps oversized item text after zoom in/out on Noble To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/2157573/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
