Looking Glass client crashes under Wayland

[octacian]

The Looking Glass client crashes when running on Wayland, seemingly whenever clicking and dragging something on the virtual machine through the Looking Glass client. It seems like this is specifically a Wayland issue.

Seems to occur on all Looking Glass client versions, however, the issue can be mitigated with the environment variable mentioned here: #1151 (comment)

I'm not entirely sure that this warrants a new issue in light of #1151, which seems to be similar, but I've opted to open a new one as the actual error message seems to be somewhat unrelated.

Host log does not appear to be applicable as [Capture Start] looks normal but [Capture Stop] is just blank.

This is the identical issue to #1151, closing as duplicate

[octacian]

👍 sounds good, my bad on the duplicate issue then. Thanks!

[daitj]

#1151 is about explicit sync, error 5

wp_linux_drm_syncobj_surface_v1#57: error 5: explicit sync is used, but no release point is set

I still get this error 3 in wayland with explicit sync disabled, this error is not a duplicate. I tried both egl and opengl.

wp_linux_drm_syncobj_surface_v1#65: error 3: Release or Acquire point set but no buffer attached

This is the command I used

__NV_DISABLE_EXPLICIT_SYNC=1 looking-glass-client-b6 -g egl win:title=lg-win -f /dev/kvmfr0 -F spice:clipboard=no -p 5900 app:allowDMA=no

It could very well be NVIDIA's driver bug because if I use NVK (from mesa, open source NVIDIA driver) it works fine. But just putting it here so that solutions could be discussed. I cannot say which action exactly causes this, but always happens when I am interacting with the client. Doesn't happen If I do not interact with client.

It seems like it has been discussed here as well:
NVIDIA/egl-wayland#149
