Full screen browsing mode doesn't work right in GNOME
For some reason, entering full screen browsing mode (by pressing F11, Ctrl-Shift-F, or from the View menu) on GNOME causes the screen to flicker and the window to not be drawn correctly. This is likely some conflict between the KDE 5 Framework and GNOME. Testing was only done on Wayland, so it might work correctly on X11. In any case, this is likely a problem that sorts itself out over time with updates to KDE Framework and Gnome. If it doesn't take care of itself, especially with the switch to KDE 6, I will dig into it deeper.
