I've bought the FF DLC and so I'm on the latest patch version but some versions ago already I ran into this problem: when I'm in the game and press F12, I get a message window popping up in the lower right of the screen stating that my screenshot has been saved immediately followed by another window stating it could not be saved. When I check the folder

c:\Users\MyUsernameHere\Documents\GOG Galaxy\Screenshots\Dead Cells\

there are files that don't look like '2019-03-29_1117_1.png' but like this: '2021-02-12_1925_1.png.tmp'. The funny thing is, when I rename them to png the files are okay and can be opened. So how come, GOG Galaxy 2.0.35 Hotifx on Windows 10 cannot rename the files properly when writing the tmp files to the harddrive works just fine?

Im looking for my Batman Arkham Knight screenshots. In the folder are only these stupid .tmp files.
And I can't open them at all. Even if I rename them.
The Baldurs Gate 3 screenshots are working fine, are even saved in a normal format.
So I dont know what happened here.

Overall is the screenshot system of GOG just not working for me. I have to search for the folder and now this strange unuseable format.
