CudaText 1.221.5.2 Qt6 Glitches on Exit

The two most recent Qt6 releases of CudaText running on Qt6 6.8.2 packages from Void Linux give segfaults and exception errors on exit. CudaText otherwise works. Note that I use the prebuilt libQtPas, which is not from Void Linux. About box says: CudaText 1.221.5.2, linux-x86_64-qt6, fpc 3.2.3 and here's my $LD_LIBRARY_PATH:

Code: Select all

libQt6Pas.so.6
libQt6Pas.so.6.2.10
libQt6PrintSupport.so.6
libQt6PrintSupport.so.6.7.2
libcupsprintersupport.so
Terminal messages (Gtk warnings are right, permission is denied for all apps):

do you see the same error on this primitive demo?
if yes, we have ready bugreport.
I added debug info there. binary size is 26M. maybe it can show more error details.

Yes it's the same error. Clicking "memo" gives mouse-popup notices. Exit gives the exception. The checkbox did nothing on stdout or stderr.

Testing details: The prebuilt libQtPas files are in "libs_needed" folder. The initial Qt warning relates to $QT_SCALE_FACTOR_ROUNDING_POLICY which is "RoundPreferFloor" in my environment.

Code: Select all

$ LD_LIBRARY_PATH="/tmp/test/libs_needed" /tmp/test/project1 
setHighDpiScaleFactorRoundingPolicy must be called before creating the QGuiApplication instance

Qt 6.8.3 should contain fix.

Solved?

Well, maybe, but I'm not sure. QTBUG-130895 says it affects 6.8.0 but is fixed in 6.8.2, which is my (Void Linux) version. I may have encountered another bug, or QTBUG-130895 is not actually fixed in 6.8.2, i.e. the bug status is wrong. For example, a race condition will vary from one machine to another. Maybe the developers testing the bug got a different race result than me, and assumed it was fixed.
