application window of qt5-based apps can't be moved around by touchscreen
Last modified: 2023-09-12 02:25:03 UTC
In Gnome desktop, when I attempt to move around the application window of a qt5-based app (like vlc, picard) by dragging the titlebar with finger on my touchscreen display, the touchscreen will immediately stop functioning (any finger tapping is noneffective now). And if I move my mouse now, it turns out that the mouse is already gotten into dragging mode, and the windows will move, and the touchscreen will get back to function after I finish the dragging. GTK apps and qt6-based apps work fine.
I see someone has reported the bug to gnome gitlab. https://gitlab.gnome.org/GNOME/mutter/-/issues/2897
