Qt

a real mess: permanent scrolling of GTK errors in console, unusable because
printing errors takes all cycles (15 sec. to stop after hitting 'Quit')

Strangely, today the delay is only ~0.6 sec (weird: no X restart, no reboot,
no more charge than yesterday, no more more (more or less:))

Yeah, I see what you mean; but I don't see how you made it (got some code?)

Ok I've got the overall.
1st I'll finished the application, and if this last, I'll contact you.

Thanks Doriano
