I think on Wayland, since the scaling is performed by the compositor, another option becomes available, which is to completely change the geometry. Instead of: +---+---+ | A | B | +---+---+ | C | +---+ It will look like +---+---+ | A | B | +---+---+ | | | C | +-------+ The important difference is how the mouse moves across the screen and how windows overlapping screens are displayed. Solving this problem is outside Qt's scope. But the case of linear arrangement of screens can be solved. The only questions are whether it's necessary to solve it to get the currently-broken applications fixed and if it is, how to detect the cases where we can and when to give up. -- 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
