What where you doing when this panic triggered?

Is that right after the start or were you actually copying something from the window or pasting something into the window when this triggered?

araraloren · 2023-12-06T13:54:30Z

@hunger Nothing.
I try to debug it, I can see the window is display. But then it is crashed.

hunger · 2023-12-06T17:05:26Z

So no user interaction (besides maybe the mouse moving). Strange.

My first suspicion without having looked into this much would of course be a problem in the smithay-clipboard crate, but of course we might just be using it wrong:-)

You could try using the Qt backend for slint (installing Qt6 into the WSL changeroot before building slint should suffice). That has very different code paths from the winit-based code we use elsewhere. That might at least get you around this problem so that you are not blocked on it.

araraloren · 2023-12-07T10:02:08Z

Okay, I will try.

araraloren · 2023-12-07T10:32:36Z

@hunger It is working with dependence configuration slint = { version = "1.3", features = ["std", "backend-qt", "compat-1-2"], default-features = false}.

ogoffart · 2023-12-08T11:27:42Z

As @hunger said, the panic is inside the smithay-clipboard crate which is used indirectly by our winit backend via the copypasta crate to get the clipboard on Wayland.

So IMHO this is a bug in smithay-clipboard and it should be reported there.

tronical · 2023-12-11T07:43:34Z

The error message suggests that the peer that provides clipboard-data is not alive anymore (so the FD transfer fails). That's a little weird though. @araraloren did you do anything with your clipboard before launching? What happens if you select text in say a web browser or terminal, copy it into the clipboard, and then start the app?

@tronical I have something similar:

fatal runtime error: failed to initiate panic, error 5
The program '[7375] test.dll' has exited with code 0 (0x0).

Even having stuff on the clipboard the error occurs.

araraloren · 2023-12-21T14:41:45Z

The error message suggests that the peer that provides clipboard-data is not alive anymore (so the FD transfer fails). That's a little weird though. @araraloren did you do anything with your clipboard before launching? What happens if you select text in say a web browser or terminal, copy it into the clipboard, and then start the app?

Yes, it's working if I clean the clipboard from clipboard settings of Windows.

interesting, for me this does not work. Could you please share the Windows and WSL 2 version?

Upstream bug: Smithay/smithay-clipboard#52

ogoffart · 2024-01-22T12:45:54Z

Closing as this is a bug upstream and we can't do anything in Slint

tronical · 2024-02-19T10:55:55Z

So this turned out not to be a bug in smithay-clipboard. It just happened to panic, but the root symptom is that the Wayland connection breaks off. Afaics Weston crashes. Have yet to find out why.

microhobby · 2024-02-19T14:55:53Z

hey @tronical, so this Smithay/smithay-clipboard#54 will not fix from the Slint side?

tronical · 2024-02-19T15:13:44Z

That's correct. It allows for better error propagation, but what's crashing is Weston. I haven't figured out yet why. Perhaps I can file a ticket with wslg - Weston should not crash. The clipboard is a red herring.

As to workaround: I don't know any yet :(.

microhobby · 2024-02-19T22:21:10Z

I think that I figure out a workaround:

WAYLAND_DISPLAY= slint_app

Unsetting the WAYLAND_DISPLAY appears to fix the panic. The point against it is that it will use the X11 as a fallback.

tronical · 2024-07-22T12:13:21Z

This is worked around now with #5657 until we have #5667 in place.
