Blockbench 5.0.3 doesn't start on wayland with flatpak

[swip3798]

What are you trying to do, and what do you expect to happen?

I have block bench installed via Flatpak. I updated it to the latest version. I tried to start it but it closed after a few seconds. I tried starting it via flatpak run net.blockbench.Blockbench.

What happens instead?

The following error comes up when starting blockbench via the flatpak run command.

[3:1026/154723.579584:ERROR:dbus/bus.cc:408] Failed to connect to the bus: Failed to connect to socket /run/dbus/system_bus_socket: No such file or directory
[3:1026/154723.776782:ERROR:ui/ozone/platform/wayland/host/wayland_connection.cc:197] Failed to connect to Wayland display: No such file or directory (2)

[3:1026/154723.776853:ERROR:ui/aura/env.cc:257] The platform failed to initialize.  Exiting.

I found that when I changed the flatpak permissions with Flatseal and added the socket=wayland permission, blockbench starts. The dbus error can be removed with adding the socket=system-bus permission.

Experiencing the same issue on Bazzite 43.

Thank you for the workarounds.

For me, it also helped to add permissions for:

--socket=wayland
--socket=fallback-x11
--socket=system-bus

oh it's doing something, using up 100% of my steam deck's gpu upon opening then quitting manually in system monitor. 5.0.4 had to force quit (kill).

For me at least worked enabling the system-bus and disabling the fallback-x11, with wayland and x11 permissions is fine.

In journalctl just appears as a simple core dumped with the next description: Stack trace of thread 3: #0 0x0000564852c45cde n/a (n/a + 0x0) ELF object binary architecture: AMD x86-64
