Bug description

I can't drop files into any chat

Additional context

No response

Most likely a duplicate of #371, #435, and #459, unless you have original CSP settings (i.e. everything toggled on).

[neondeex]

I have all in default and i can upload media but i can't drag and drop anything

[crabreader]

Can confirm that I also have this issue, some UI elements become unresponsive when I try to drag and drop files into a chat (cant switch channels, cant type in the chatbar). If switch server it resets and becomes responsive again.

[SpacingBat3]

Cannot reproduce it on my end though, at least on Electron 26…
What packaging method are you using @neondeex? Also @crabreader are you on the same major version of Electron (i.e. 25) or different?

[neondeex]

I use the AUR version

[SpacingBat3]

@neondeex Also, are you on Wayland, XWayland or X11?

[SpacingBat3]

I use the AUR version

I've tested the build (webcord) from chaotic-aur, things are OK with that…
Also, did you double-checked that Google Storage isn't being disabled for sure in WebCord's settings?

[crabreader]

I use electron from the arch extra repository, it seems to be version 25. When I tried to install electron 26 I was unable to make webcord run using that version, I don't know how to build webcord with a specific version of electron.

Also it might be of note that I am using wayland with a nvidia graphics card.

[crabreader]

My issue appears to be related to xwayland, I managed to build webcord with electron26 but I didnt realize that it runs under xwayland. I get an error like this when I attempt to drag a file:

[82368:0912/175748.813949:ERROR:x11_drag_context.cc(150)] XConvertSelection failed for source-advertised target 540

[SpacingBat3]

My issue appears to be related to xwayland, (...)

@crabreader What about running app in Wayland (--ozone-platform-hint=auto or --ozone-platform=wayland)?

[crabreader]

@SpacingBat3 Can confirm that it works when i run webcord with that flag, but I also need to use --disable-gpu for it to launch. I don't know if that can lead into other problems.

I can reproduce this on X11 using the Flatpak.
Using the + button and manually picking the file instead of drag&drop works fine.

@dreamsyntax That one is actually a problem specific to Flatpaks (or Electron, if there's any app actually functional with drag&drop packaged as Flatpak?) since there's sandboxing going on and it is very likely that drag and drop doesn't work via portals like when adding a file via native dialogs.

I have been having this problem as well. However, I have this issue using Discord (Arch-packaged) Chromium as well. So it might be a Chromium bug. I'm not sure it is a problem with WebCord, as it happens in default Discord as well.

For reference, I am using a wlroots compositor, specifically Hyprland. It would be interesting to see if the issue is related to that.

edit: for extra confirmation, Discord website in Firefox does not have this issue.

(…) I'm not sure it is a problem with WebCord, as it happens in default Discord as well.

It definitely isn't. But I'll track it here. I doubt I can do anything to fix it, it sounds to be highly specific to Wayland and given I don't use a Wayland-based DE nor Chromium is supporting it as a stable, it is unlikely I'll came with some workaround. Possibly reporting this to upstream (i.e. to Chromium or Electron devs) is what should be done.

[lambdcalculus]

Oh, just confirmed that --ozone-platform=wayland works for me on both Discord and WebCord, along with Discord in Chromium. I thought I had already done it before, but actually hadn't done it properly: kill all Discord/Webcord/Electron instances before relaunching, otherwise it will run on Xwayland which seems to be the cause of the broken drag-and-drop. Make sure the window does not open as Xwayland and it should work fine.
