Idk about the gpu screen recorder but for the keychain for Discord if you disable the KDE wallet subsystem (which is just in the kde system settings) it should stop asking. it’s never caused me an issue and made the discord popup go away. its a dirty solution but its what worked for me.

I recommend The Decursio Project if youre looking for an in depth industrial modpack (it does require magic, if thats a deal breaker). it has minecolonies too. Im running a private server on it right now and its the best mod pack ive ever played, though i did disable the “ages” mechanic and im not doing the quests, just using them as a reference.
