Drag & drop doesn't work on Fedora 40 / Wayland #57

Closed deusnovus closed 5 months ago

deusnovus commented 5 months ago

I'm currently working on a one-click Bitwig Studio / xjadeo sync situation, so while trying the latest xjadeo binary on Linux, I noticed that drag & drop doesn't seem to work.

I tried dragging .mp4 and .mov files right onto xjadeo's window and while the cursor displays a + sign, it yields nothing. Running it via terminal also does not display any additional information upon doing so.

Any suggestions would be graciously appreciated, thank you.

If I had to guess... it's likely an issue with XWayland. Here on debian with Xorg DnD works.

Can you open a video using the context menu > File > Open Video (ctrl+o), or specifying it on the commandline?

deusnovus commented 5 months ago

Yes, opening a video through the menu works great, no problem there! This issue mostly pertains to the drag and drop feature.

Could this feature be implemented on XWayland?

x42 commented 5 months ago

I don't know. XWayland is supposed to be compatible with X11, yet searching the web for "Xwayland Drag Drop" finds a couple of issues and various applications are affected.

There are currently no plans to port xjadeo to wayland wjadeo. So if the issue is Xwayland specific (and not something else on Fedora 40 or your WM/system), it needs to be resolved by the XWayland team.

I see... I also searched the web for "xwayland drag drop", but results vary on a case-to-case basis.

Are there any additional boot arguments I can include in my xjadeo.desktop, in order to force xjadeo to properly interact with xwayland?

I understand xjadeo is intended to work primarily with X11-based environments, so I really appreciate you taking the time to discuss Fedora and xwayland.

EDIT1: I also reported this on the xserver repo, as suggested.

EDIT2: This could very well be a Mutter bug: https://gitlab.gnome.org/GNOME/mutter/-/issues/3511 I suppose I should close this issue then, but feel free to reopen, if needed.
