Description

Hyprland's Implementation of the wlr-data-control-unstable-v1 protocol handles reporting selections for images improperly. On Hyprland, when using a script to listen for non-text clipboard events, the protocol returns a 4byte array which seems to be some sort of memory-address rather than the contents of the image as expected.

Here's an example of a script running on hyprland after copying a few images:

ClipBoardListenMessage { mime_types: ["text/plain;charset=utf-8", "text/plain", "TEXT", "STRING", "UTF8_STRING", "SAVE_TARGETS", "MULTIPLE", "STRING", "text/plain", "text/plain;charset=utf-8", "text/plain", "text/plain;charset=utf-8"], context: Text("") }
ClipBoardListenMessage { mime_types: ["SAVE_TARGETS", "MULTIPLE", "image/png", "text/html"], context: File([121, 62, 236, 1]) }
ClipBoardListenMessage { mime_types: ["SAVE_TARGETS", "MULTIPLE", "image/png"], context: File([111, 80, 236, 1]) }
ClipBoardListenMessage { mime_types: ["SAVE_TARGETS", "MULTIPLE", "image/png", "text/html"], context: File([225, 104, 236, 1]) }

The contents of context: File([...]) should contain the entire contents of the image which is the behavior on other compositors like sway.

How to reproduce

1. Run Hyprland Compositor.
2. Use a tool to listen for non-text clipboard events such as https://github.com/imgurbot12/hyprland-clipboard-test
3. Watch logged events for invalid clipboard-data

I know this same library works on sway so I'm not sure why its having trouble finding a data_device.

[v4u6h4n]

Not sure if my issue is related, but my clipboard broke for vscodium after the update, everything else seems to work fine. Related or shall a post a separate issue?

[vaxerski]

possibly related

[v4u6h4n]

Okay. It's kinda strange... I've tested all the other applications I use regularly, and they all work fine, its only vscodium. And I can paste to vscodium from other applications, but if I copy within vscodium it wipes the clipboard.

[vaxerski]

what app are you using? I opened an image in nomacs, and copied buffer, then image, and got this:

which looks correct

[imgurbot12]

I've used brave-browser, vencord, signal-desktop, and gimp to copy images all with the same issue.
Copying the actual image works most of the time, but the actual selection reporting from the protocol always returns the 4byte array.

Edit: Interestingly, copying buffer using nomacs works as intended vs all the other apps I've used.
Edit: I thought some of the apps I was using were native wayland apps but it turns out all of them are likely XWayland. Maybe it has something to do with that bridge for whatever reason.
Edit: forcing brave-browser to run in wayland native mode with some experimental flags fixes the issue so its almost definitely XWayland related

[vaxerski]

I'll just pin it under #6247 then.

XWayland's clipboard is buggy and incremental copying is not supported so it's very likely it's that.

likely "wontfix", please switch to using wayland. all of the above apps can use native wayland.

XWayland's clipboard is buggy and incremental copying is not supported so it's very likely it's that.

I see, that's rather unfortunate. If that's the case then I have another bug to report which I will open an issue for lol. brave-browser running directly under wayland has a lot of very weird artifacts and issues under Hyprland that I have not seen using sway.

Here's a short vid demonstrating some of them I've encountered in just the small bit of testing I've done.

I'm not sure that all the apps I use have native wayland alternatives so It sounds like I may need to move back to sway until some of these things get fixed or a solution is found :/

Edit: issue created at #6524

[v4u6h4n]

I'll just pin it under #6247 then.

XWayland's clipboard is buggy and incremental copying is not supported so it's very likely it's that.

likely "wontfix", please switch to using wayland. all of the above apps can use native wayland.

Switched vscodium over to wayland and it fixed the clipboard, so seems like your right.

Oh damn, i need chatterino for my stream, and it doesnt work with wayland currently, hopefully it can be reopened at a later date; even outside of my specific use case, being able to use legacy x11 applications in the future would be useful.
