Bug#1061719: libqt6gui6:amd64: QT_QPA_PLATFORM=xcb doesn't seem to work
Package: libqt6gui6
Version: 6.4.2+dfsg-10
Severity: normal
X-Debbugs-Cc: none, Janusz S. Bień <jsbien@mimuw.edu.pl>
File: /usr/lib/x86_64-linux-gnu/qt6/plugins/platforms/libqxcb.so
A program which works correctly on X is crippled on Wayland, one of the
panels is not opened. I was advised to use xcb, but it does not have any
effect.
More information at the thread:
https://forum.qt.io/topic/154144/debian-after-upgrading-the-system-the-program-became-unusable-how-to-approach-the-problem/13?_=1706499698799
BTW, when reporting this problem with Emacs debian-bug I got a strange
warning that libqt6gui6 is not installed although apt install reports
"libqt6gui6 is already the newest version (6.4.2+dfsg-10)." Quite
possible that my QT installation is somehow messed up (I use it only for
compiling two QT programs). qtchooser reports 7 versions: 4 5 default
qt4-x86_64-linux-gnu qt4 qt5-x86_64-linux-gnu qt5. QTCreator reports
5.15.8 twice: /usr/lib/qt5/bin/qmake and
/usr/lib/x86_64-linux-gnu/qt5/bin/qmake.
I will appreciate your help
JSB
