Created attachment 148394 [details] text of drqonqi report Application: plasmashell (5.18.6) Qt Version: 5.12.7 Frameworks Version: 5.76.0 Operating System: Linux 5.3.18-150300.59.63-default x86_64 Windowing system: X11 Distribution: openSUSE Leap 15.3 -- Information about the crash: - What I was doing when the application crashed: Plasma5 crashes with the same SegFault (11), every time my desktop goes into screensaver (or comes out of it - difficult to tell exactly when) new additional note: it crashed again while I was filing this bug and even Alt+SysRq_S/U/B didn't work. Hard power off. Then when I rebooted it happened again but this time didn't freeze everything. In case I didn't already mention it. Every time I boot, the first thing I see in the GUI is an unreportable error where ksplashqml has crashed. Report is in the attachment

Unfortunately your Qt version is quite ancient. I would recommend upgrading to Plasma 5.24 and Qt 5.15.3 and trying again.
Created attachment 148790 [details] smime.p7s I reinstalled OpenSUse Leap 15.3 (which is a current LTS release, I believe), so should be sufficiently current until 15.4 turns up. If this is an issue, then it’s questionable whether SUse are doing a competent job for their LTS release. In the meantime, I’ve switched to OpenSUse Tumbleweed, which seems to have fixed the issue. > On 27 Apr 2022, at 17:13, Nate Graham <bugzilla_noreply@kde.org> wrote: > > https://bugs.kde.org/show_bug.cgi?id=453064 > > Nate Graham <nate@kde.org> changed: > > What |Removed |Added > ---------------------------------------------------------------------------- > CC| |nate@kde.org > Status|REPORTED |RESOLVED > Resolution|--- |UNMAINTAINED > > --- Comment #1 from Nate Graham <nate@kde.org> --- > -- Backtrace: > Application: Plasma (plasmashell), signal: Segmentation fault > [KCrash Handler] > #4 std::__atomic_base<int>::operator++ (this=0x7f34555672a8) at > /usr/include/c++/7/bits/atomic_base.h:296 > #5 QAtomicOps<int>::ref<int> (_q_value=...) at > ../../include/QtCore/../../src/corelib/thread/qatomic_cxx11.h:265 > #6 QBasicAtomicInteger<int>::ref (this=0x7f34555672a8) at > ../../include/QtCore/../../src/corelib/thread/qbasicatomic.h:114 > #7 QtPrivate::RefCount::ref (this=0x7f34555672a8) at > ../../include/QtCore/../../src/corelib/tools/qrefcount.h:61 > #8 QString::QString (other=..., this=<optimized out>) at > ../../include/QtCore/../../src/corelib/tools/qstring.h:958 > #9 QFontEngineMulti::fallbackFamilyAt (at=<optimized out>, > this=0x7f3400130ee0) at > ../../include/QtGui/5.12.7/QtGui/private/../../../../../src/gui/text/qfontengine_p.h:495 > #10 QFontEngineMulti::loadEngine (this=0x7f3400130ee0, at=<optimized out>) at > text/qfontengine.cpp:1832 > #11 0x00007f347c69390d in QFontEngineMulti::ensureEngineAt > (this=this@entry=0x7f3400130ee0, at=at@entry=221) at text/qfontengine.cpp:1819 > #12 0x00007f347c6c6c42 in QTextLine::glyphRuns (this=this@entry=0x7f3409407480, > from=from@entry=0, length=<optimized out>) at text/qtextlayout.cpp:2407 > #13 0x00007f347ff69dbc in QQuickTextNodeEngine::addGlyphsInRange > (this=this@entry=0x7f3409407420, rangeStart=rangeStart@entry=0, > rangeLength=rangeLength@entry=41, color=..., backgroundColor=..., > selectionStart=selectionStart@entry=-1, selectionEnd=-1) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/items/qquicktextnodeengine.cpp:593 > #14 0x00007f347ff6a347 in QQuickTextNodeEngine::addGlyphsForRanges > (this=this@entry=0x7f3409407420, ranges=..., start=start@entry=0, end=41, > selectionStart=selectionStart@entry=-1, selectionEnd=selectionEnd@entry=-1) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/items/qquicktextnodeengine.cpp:565 > #15 0x00007f347ff68b7a in QQuickTextNode::addTextLayout > (this=this@entry=0x7f34002ffc40, position=..., textLayout=0x563c7333e050, > color=..., style=QQuickText::Normal, styleColor=..., anchorColor=..., > selectionColor=..., selectedTextColor=..., selectionStart=-1, selectionEnd=-1, > lineStart=0, lineCount=1) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/items/qquicktextnode.cpp:268 > #16 0x00007f347ff6762c in QQuickText::updatePaintNode (this=0x563c73331b20, > oldNode=<optimized out>, data=<optimized out>) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/items/qquicktext.cpp:2440 > #17 0x00007f347ff17238 in QQuickWindowPrivate::updateDirtyNode > (this=this@entry=0x563c7101d910, item=item@entry=0x563c73331b20) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/items/qquickwindow.cpp:3524 > #18 0x00007f347ff17ac3 in QQuickWindowPrivate::updateDirtyNodes > (this=this@entry=0x563c7101d910) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/items/qquickwindow.cpp:3269 > #19 0x00007f347ff18e42 in QQuickWindowPrivate::syncSceneGraph > (this=this@entry=0x563c7101d910) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/items/qquickwindow.cpp:437 > #20 0x00007f347febfa94 in QSGRenderThread::sync > (this=this@entry=0x563c71dac160, inExpose=<optimized out>) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/scenegraph/qsgthreadedrenderloop.cpp:563 > #21 0x00007f347fec0ea4 in QSGRenderThread::syncAndRender > (this=this@entry=0x563c71dac160) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/scenegraph/qsgthreadedrenderloop.cpp:610 > #22 0x00007f347fec4738 in QSGRenderThread::run (this=0x563c71dac160) at > /usr/src/debug/libqt5-qtdeclarative-5.12.7-4.2.1.x86_64/src/quick/scenegraph/qsgthreadedrenderloop.cpp:730 > #23 0x00007f347bde4132 in QThreadPrivate::start (arg=0x563c71dac160) at > thread/qthread_unix.cpp:361 > #24 0x00007f3478c426ea in start_thread () from /lib64/libpthread.so.0 > #25 0x00007f347b625a8f in clone () from /lib64/libc.so.6 > > This indicates that the issue is in Qt.
