A customer is reporting the following warning with his Qt installation:
And indeed, the LinuxFB integration lacks an implementation of the virtual QPlatformCursor::setPos() function.
Looking at the existing qfb*.cpp code it seems like all everything needed might already be there. That means a reimplementation of setPos() with 1-2 lines triggering the needed changes might be sufficient. I apologize for not having the setup to fix that myself.
