    Description

      There is a bug in the Qt 5.14 beta 2 that prevents Qt Quick apps from working: QTBUG-79497

      Since it looks like the bug would be no problem if Qt was built with multithreading support I rebuilt Qt from source with "-feature-thread". The apps build with multithreading just fine now, but on compiling in the browser they just eat up all memory until the tab crashes.

      Not quite sure how to debug something like that, the developer window in the browser shows no hint at the problem.
