Copy/Paste not working for GOG Sources login

I cleaned out some cache files recently and was logged out of GOG in Lutris. I use KeePassXC for all of my logins, and couldn’t paste my username or password into the pop-up login window.

Lutris itself accepts clipboard pasting (e.g. the Lutris Sources login), and I can copy and paste text within the GOG login popup.

Going through the forums, I found a similar post from a few years ago, but that bug was seemingly solved. I haven’t had this issue in the past (same OS, same method), so I’m not sure where the problem lies.

Update: I was able to paste my password into Lutris after first pasting then re-copying it from a text editor (I used leafpad). The bug must have to do with the way Lutris interacts with KeePassXC.
