Bug 252773: x11-toolkits/qt5-gui: Segfault on applications using qt5
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252773
--- Description ---
Hello,
This bug is related to bug #247991.
I have upgraded my system to last 12.2 and last ports with the same result. All
qt5 applications crash with Segmentation fault (DRI2) or Bus error (DRI3+SNA).
I have tried to rebuild qt5 (5.15.0) from sources to have debug symbol,
backtrace is :
(gdb) bt
#0 0x000000080163fa20 in qt_memfillXX_avx2(unsigned char*, long long
__vector(4), long long) () from /root/qt5/lib/libQt5Gui.so.5
#1 0x00000008018bc2d5 in fillRect_normalized(QRect const&, QSpanData*,
QRasterPaintEnginePrivate*) () from /root/qt5/lib/libQt5Gui.so.5
#2 0x00000008018bdcd6 in QRasterPaintEngine::fillRect(QRectF const&,
QSpanData*) () from /root/qt5/lib/libQt5Gui.so.5

#4 0x00000008010c04be in fillRegion(QPainter*, QRegion const&, QBrush
const&)
() from /root/qt5/lib/libQt5Widgets.so.5
#5 0x00000008010c017f in QWidgetPrivate::paintBackground(QPainter*,
QRegion const&, QFlags<QWidgetPrivate::DrawWidgetFlag>) const ()
from /root/qt5/lib/libQt5Widgets.so.5
Similar issue with qt5 5.14.2. Of course, I have tried to rebuilt qt5 with
different build options without any success. My graphic adapter is internal GPU
of a i5-4570S CPU.
xorg.conf :
Identifier "Card0"
Driver "intel"
BusID "PCI:0:2:0"
Option "AccelMethod" "SNA"
Option "DRI" "3"
