Letting the display turn off naturally doesn't seem to produce this bug. Locked the screen, waited 10+ mins, woke up the display, and it was fine. Manually turning it off using ESC always produces this problem though.
Apparently, this affects more applications than just kscreenlocker. I've just had kded5 crash with a very similar backtrace. It seems to me that something in libkscreen is causing this problem. To my knowledge, this wasn't an issue in 5.27.1, so I'm marking this as a regression. Here's the backtrace of kded5: [Thread 0x7fc3c67fc6c0 (LWP 172357) exited] [Thread 0x7fc3c7fff6c0 (LWP 172354) exited] [Thread 0x7fc3e57fa6c0 (LWP 172352) exited] [Thread 0x7fc434cc26c0 (LWP 172339)

I've been looking into this. Testing didn't bring any crashes. While your assessment that it might be the placeholder screen kicking in, at the moment we are already testing for wl_output being null, which should be a symptom of the placeholder hitting us. I've put together the following patch for libkscreen, would you be able to apply it on top of libkscreen? To test you can use kscreenlocker like you said. Running "/usr/lib/libexec/kscreenlocker_greet --testing" will make it possible for you to reproduce it without being locked out of the session. Thank you!!! ---- diff --git a/src/libdpms/waylanddpmshelper.cpp b/src/libdpms/waylanddpmshelper.cpp index 021dbf5..32259e1 100644 --- a/src/libdpms/waylanddpmshelper.cpp +++ b/src/libdpms/waylanddpmshelper.cpp @@ -114,8 +114,11 @@ private: { QPlatformNativeInterface *native = qGuiApp->platformNativeInterface(); wl_output *output = reinterpret_cast<wl_output *>(native->nativeResourceForScreen(QByteArrayLiteral("output"), screen)); + qDebug() << "about to crash?" << screen << output << native; if (output) { - m_dpmsPerScreen[screen] = new Dpms(get(output), m_dpms, screen); + auto x = get(output); + qDebug() << "boom" << x; + m_dpmsPerScreen[screen] = new Dpms(x, m_dpms, screen); } }

So here's a fix in Qt, I'll add a workaround until we can rely on this... https://codereview.qt-project.org/c/qt/qtwayland/+/464669
A possibly relevant merge request was started @ https://invent.kde.org/plasma/libkscreen/-/merge_requests/115
I confirm the workaround fixes the issue for me (I had applied https://invent.kde.org/plasma/libkscreen/-/commit/00d8e90f821123f04fcb7ea39724a1f221a76f37 before as well)
