This is an extremely annoying issue. Recently i updated my OS from openSUSE 13.2 x86-64 to openSUSE 42.2 x86-64. The main difference is the Desktop Environment, which is upgraded to an other major version, i.e Plasma 5 / KDE5. (vs KDE 4 previously).
Since this upgrade i cannot debug anymore my main application. Each time i click to open a main menu, the desktop freezes. Then i have to go to TTY6, pkill gdb, and back to the graphical environment, where everything works fine again (excepted that debugging is finished).
So far i tried to
- disable Exception catching in the application TApplication instance.
- disable events assigned to onUpdate of the actions assigned to the menu items.
- disable all desktop effects.
- reproduce on a simple application
But none of the measure fixed the issue. The simple application was not subject to freezes during debugging.
Any idea of the problem origin ?
