Whenever taking a screenshot, the mod tend to auto-copy the screenshot in the clipboard
But it throws an error after a screenshot was taken

Manually copying the screenshot also doesn't get the lastest screenshot in the clipboard
The HUD and Interface work fine

Here's the error that I was able to reproduce: https://imgur.com/a/y0Wcv0B

Tiny update on this, there's a experimental build on forge version that could fix definitely this issue without impacting any other mods, should be coming on fabric in the following days

Hey ! Thanks for your feedback !
Indeed, the error is somehow intended, since if I do not throw an error this way, the game crashes.

This is a difficult /impossible bug to fix, since I do need some APIs inside Java that are probably changed by some optimization / client side mod that you use.

Apparently the error isn't explicitly made when you try to copy the latest screenshot with the key binding, I'll fix that in next release. 😄

Since you mentioned about client-side mods that I used, I guess I should have linked a screenshot of my modpack, my bad.
Here are the mods that I used, hope it helps!

There's many mods that could impact that, and unfortunately I think if they changed what I do need for their own purposes, it's because they need it too.

I hope someday I'll find a solution about it, but for now despite hours on this clipboard feature, I haven't been able to come out with another solution 😅

Sorry for bumping this. I came back after 2 months, trying the mod again, well it sort of working right now
My hotkey for copying the lastest screenshot taken is "Y", I took a screenshot then press the "copy to clipboard" hotkey to try to paste it into Discord, but it throws an error
On the other hand, the copy in the UI works fine

I'll take a look, thanks !

Sorry, again, for bumping
I found the issue causing Nicephore to not able to copy the screenshot into the clipboard using hotkey

So I realized I was using Fabrishot to overwrite the the vanilla screenshot, apparently Nicephore only recognize vanilla screenshots, but as soon Fabrishot overwrites it with its own screenshot function, the "copy to clipboard" stopped working and throw the error just like in the video I sent

Just to recognize how Fabrishot overwrites vanilla screenshot, the video 12 days ago I sent above also show me took a screenshot, as a flash occured, that was Fabrishot overwrite function, which is togglable in the settings

So for now, I think making a compatible with Fabrishot should help, or depend on the player, like me, to not use the overwrite function and just let the mod capture screenshot with a different hotkey beside vanilla one (default for the mod is F9, vanilla is F2)

Hey, thanks for the feedback, I just posted a quote of you investigation on they issues tracker, we'll see what's possible about it. :)

@LotuxPunk Are you still interested in fixing this?
