      Description

      Qt applications (tested with telegram, reproduced with a minimal example ) ignore modifiers for key combinations containing shift/alt+gr (e.g. alt+gr+' with the Italian keyboard should output a backtick, but outputs a single quote instead).

      Culprit (found with bisect) 6b8083a265fc012b28178b8fab619062e43a458a, (
      https://github.com/qt/qtbase/commit/6b8083a265fc012b28178b8fab619062e43a458a) 

      The minimal example code:

      #include "QtWidgets/QApplication"
      #include "QtWidgets/QTextEdit"
      
      int main(int argc, char *argv[])
      {
          QApplication a(argc, argv);
          QTextEdit Editor;
          Editor.show();
      
          return a.exec();
      }

      Output of setxkbmap -print

      19:54  ~  $ setxkbmap -print 
      xkb_keymap {
      	xkb_keycodes  { include "evdev+aliases(qwerty)"	};
      	xkb_types     { include "complete"	};
      	xkb_compat    { include "complete"	};
      	xkb_symbols   { include "pc+it+inet(evdev)"	};
      	xkb_geometry  { include "pc(pc105)"	};
      };
