SUMMARY
Hey there,

I recently switched from x11 to wayland, but latte always either crashes when trying to start it or when trying to creaste a new panel.
Here's the log: https://pastebin.com/7bBQhS6t

I have an nvidia GTX 1080 with proprietary graphics drivers installed and I'm on Plasma 5.24.2 on Manjaro.
I already tried to delete the config folder of latte.
Should any additional information be required, I'd be happy to help!


STEPS TO REPRODUCE
1.  start Plasma in wayland session
2.  try to start latte-dock
3.  observe

OBSERVED RESULT
latte crashes

EXPECTED RESULT
latte doesn't crash

Oh sorry,

I've attached a picture of the backtrace window.
It doesn't really seem to be a crash, but latte just "hangs" endlessly and never shows up.

I also ran the other command listed on the website.

Here's the output of env QV4_FORCE_INTERPRETER=1 latte-dock -d:

This is KScreen applet crash under wayland that is hosted probably in the systray.
If you close Latte, add a default plasma panel and relogin dont you have the same crash?

oh, that's interesting.
I already added a default plasma panel, before running these latte commands (as I wouldn't have any panel at all otherwise)
So, with default Plasma panel -> crash

I just noticed that executing "latte-dock -d --default-layout " brings up a dock that works, I can't add a panel or dock though
