*** SUMMARY Opening the game, maximize it, then exit. Or play one game and then exit. When it is re-opened, it is not maximized. SOFTWARE/OS VERSIONS Linux Mint 21.3 x86_64 Flatpak version. ADDITIONAL INFORMATION kpatrc file show all height/width settings as 1920x1080 which is right. I have opened and closed the game multiple times, played multiple games, won multiple games, viewed settings, and exited either with the "x" or with game->quit on menu.
I deleted the kpatrc file. Lost all my settings but the program still will not stay maximized when launched a 2nd time. I have to maximize every game session. It's stays maximized for the whole session. Just want to make it clear.
I switch to the non flatpak version, Version 21.12.3 and all is working fine now. So I reason it's in the newest flatpak version.
