I have just experienced a few couples of unwanted quitting while exit the designer.
But, I have (I hope!) a last question (maybe two). I still have to notice a constant bad behaviour about videos in loop and the “Rich text” formatted labels (between gallery and delegated text widget).
After some time playing on exported .exe, it seems that video starts to keep in “cache” (I don’t know how to explain it, sorry), so the source can be played not only one time, but in loops. Same behaviour for formatted text property on widget. When you tap/clic on the first image, it does not load the text of the first label but, if you go on the next and return they play correctly. Even leave and re-enter the page.
Does it is related on presentation settings for “Asynchronous”, “Load on demand” that are both checked?
I will upload again the .pma so you can take a look.
Please, after checking if the first video intro plays in loop and also on the second page (that one with hand gestures), at the third page, click on “Vincenzo Gemito” to view how, below the gallery, the label text widget works. The others artists are empty.
