My existing installation of Ubuntu Studio got seriously messed up by my adding the Unity Desktop to it. The simplest way to sort it out seemed to be a complete reinstall.
But before doing that I installed, in turn, Ubuntu Unity, vanilla Ubuntu, xUbuntu (which I rather liked) and finally, reluctantly, Ubuntu Studio again. These were all the latest 22.04 versions. In each case I then installed qtractor, with it's libraries and the qt6 stuff from ppa:rncbc/apps-jammy. The colourpicker crash was present in every case, except under Ubuntu Studio.
I also tried to use the AppImage and the flatpak versions, but unfortunately I couldn't manage to get either of them to run.
There are lots of people who are far more concerned than I am with the visual interface of qtractor, judging from the 143 posts on the subject of Theming. Nonetheless, having a button which is not only useless but causes a crash if absent-mindedly clicked (as I have been known to do) is troublesome.
Obviously there must be some reason why this crash happens. If it could be fixed, that would be fantastic.
But if it really, really can't be fixed (and I have no way of knowing), could I suggest something else? The drop-down colour chooser works tolerably well, and the required colour can be entered in hexadecimal form. Unfortunately it doesn't remember previously chosen colours (apart from the last, which it seems to use as a background). Perhaps new colours selected could be added to the drop-down list, preferably at the top. In fact, it would probably be better if each new colour were added at the top, with the bottom one being removed.
It would also be helpful if the colourpicker button could be removed. It could perhaps be a choice in the display options under the View menu.
I know none of this is terribly important (except to me and possibly a few others). But there's no harm in flagging it up, is there!
