Panning (default key settings) does not work with my 1.4 Flatpack installation on Mint 19.1 (Ubu 18.04 LTS).
When I hit any of the pan-keys, I see that the key being displayed at the bottom of the window (i.e. schematic editor) - but no other reaction, i.e. movement. Only when the mouse pointer is moved directly after the pan-key, the window content will move into the requested direction. It seems as if the pan-key requests are stored in some kind of FiFo buffer and only executed when a mouse movement is registered. Hitting any other key does not active the pan-movement.
This strange behaviour makes the installation effectively unusable, as I have no chance to navigate thru a design requiring substantial schematic area. Any idea?
