Committed on 16/05/2022 at 14:30. Pushed by ngraham into branch 'master'. Fix loading the lockscreen fallback UI kscreenlocker has a fallback UI loaded if the main QML from the LNF fails. As the main code is in a loader the lockscreen /always/ loads even if the main contents can't be loaded. It also contributes to a black flicker when loading the lockscreen. The rationale for the loader was to make the window appear faster. This hopefully isn't needed now we have the logind integration delaying the sleep. If it turns out this is feature desired it would be far more productive to do this in the greeterapp c++ code. Show an empty QtQuick window and then set the source on it later. It'd be far faster which would help towards the original goal and allow us to check the loading. This patch also removes the opacity fade as there's already an opacity fade on contents when one moves the mouse when the "screensaver" like code looks smoother.

https://bugs.kde.org/show_bug.cgi?id=370676 --- Comment #40 from nyanpasu64 --- https://github.com/qt/qtdeclarative/commit/e74bcf751495d9fe27efd195bc04e2a6ae6732a4 purportedly fixes this bug (https://bugreports.qt.io/browse/QTBUG-87190) in Qt 6. However kscreenlocker is still on Qt 5. Should this be cherry-picked to https://invent.kde.org/qt/qt/qtdeclarative/-/tree/kde/5.15 or not (now or once it's released in a stable Qt 6.x patch)? I still think kscreenlocker's behavior could be improved with or without the Qt bug fixed, and with or without virtual keyboard support installed. See my previous comment. I might get around to implementing it at some point... -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=370676 --- Comment #38 from nyanpasu64 --- I think qtvirtualkeyboard-plugin doesn't so much "fix" kscreenlocker but workaround the bug. Pressing Tab leaves the entire screen invisible, but once you move your mouse, the virtual keyboard button (not the password field) is focused, and typing your password does nothing. I think this is a bug in of itself. The bug lies in Qt Quick, where pressing Tab when *all* focusable items have invisible *parents* hangs the app. Installing the virtual keyboard causes kscreenlocker to add an extra button which itself becomes invisible while its parent remains visible (https://invent.kde.org/plasma/plasma-workspace/-/blob/0d491641f3ea148417283819994228aab6896041/lookandfeel/contents/lockscreen/LockScreenUi.qml#L523-535). This coincidentally avoids the condition necessary to trigger the Qt Quick hang bug. The upstream bug reports are: - I reported https://bugreports.qt.io/browse/QTBUG-96762 (marked as duplicate of below) - https://bugreports.qt.io/browse/QTBUG-87190 (unfixed) Qt Quick has a long history of tab focus bugs: - https://bugreports.qt.io/browse/QTBUG-81839 (marked as duplicate of below) - https://bugreports.qt.io/browse/QTBUG-81510 (fixed in 5.14.2 and 5.15.0) - https://bugreports.qt.io/browse/QTBUG-65943 (unfixed) - https://bugreports.qt.io/browse/QTBUG-59181 (fixed in 5.12.0) (And Qt Widgets has scenarios where Tab followed by Shift+Tab doesn't return to the starting widget, which is less severe than a hang. Tab navigation is hard.) Idea: When the password entry is hidden, intercept Tab presses and treat it like moving the mouse (show the lock screen and focus the password field), rather than letting Qt search for an item to focus. When the password entry is shown, let Tab switch widgets as usual. -- You are receiving this mail because: You are watching all bug changes.

Now it makes sense why it only affects X11 too, since the file that imports the Qt Virtual Keyboard module is only used on X11; on Wayland, we use a different thing.

If it's marked as such in our CMake code, then the problem is on the distro side. If not, it's our problem and we should mark it as a mandatory dependency, since it apparently is required or else the screen locker breaks. -- You are receiving this mail because: You are watching all bug changes.
