CudaText 1.221.5.2 Qt6 Glitches on Exit

[Random Void User]

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

see replies at that Laz topic. Zeljan wrote:

Qt 6.8.3 should contain fix.

Solved?

[Random Void User]

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.

When 6.8.3 will be available to you, pls test and report back.
