We will most probably move from Qt 5.6 to 5.7 with one of the next Felgo updates. The date is not fixed yet, but we expect to release it within the next two weeks. And of course, with Qt 5.7 as the base version for Felgo, all the 5.7 additions and modules by Qt will then also be available in Felgo projects. 😉
Sorry for the late reply. It is strange that the reported behavior only seems to occur on win/linux desktop. At the moment we’re quite busy with preparing the release of the Felgo Multiplayer features, so we did not yet get to have a deeper look at this issue. We will get back to you once we know more!
