More debugging: When on screen 2, the central widget in VNC mode does update if I shrink the window, but not if I enlarge it. The menu bar drop downs do draw properly and in the right position, but the toolbar extension does not. My guess is that the menu bar drop down is a separate X window while the toolbar is not. See https://bugreports.qt.io/secure/attachment/92037/ Screenshot_20200213_100723.png. I've captured a *.debug=true log of krdc in both screens, where all I did was connect (from the command-line) and draw one of the corners a little to expand, then quit. See https://bugreports.qt.io/secure/attachment/92039/krdc-screen1.log https://bugreports.qt.io/secure/attachment/92038/krdc-screen2.log I still can't find an example in qtbase that has the same issue. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
