Tapping on plasma panels is not getting registered as clicks and I think all new KF5/Plasma5 apps (such as Kwrite, Konsole) have the same problem, while apps that are not ported yet like Dolphin and Apper still works. Note: Using xev it looks like screen taps are sent like normal button press & release, but it seems like KF5, plasma5 or Qt5 does distinguish between the two! Output from xev: -------- ButtonPress event, serial 40, synthetic NO, window 0x2a00001, root 0xd6, subw 0x0, time 6149689, (164,167), root:(1098,349), state 0x10, button 1, same_screen YES ButtonRelease event, serial 40, synthetic NO, window 0x2a00001, root 0xd6, subw 0x0, time 6149761, (164,167), root:(1098,349), state 0x110, button 1, same_screen YES ------ Reproducible: Always Steps to Reproduce: 1. Run for example KWrite 2. Tap on "Open" button Actual Results: The button will have the blue highlight around it but won't open the OpenFile dialog (it reacts to it as a mouse hover only) Expected Results: The tap should be handled as a click
KWrite and Konsole are not part of the Plasmashell so we can't do much here. Sorry In any case your problem is with Qt.
Thank you David, btw, I mentioned KWrite and Konsole because they are experiencing the same behaviour as plasma, which is clear to me now since they are using Qt5. I searched in Qt bug reports and found this, which I believe is related to the issue: https://bugreports.qt.io/browse/QTBUG-46142
Thanks for finding that and reporting back, useful to know.
The problem got fix, however, it will only be applied to Qt 5.6+, since there is no more development in the 5.5 branch Patch: https://codereview.qt-project.org/#/c/125718/
