I also confirmed this issue today.

That’s how wayland works by design. Fullscreen windows can’t be transparent.

@kchibisov however it’s not working or even worse or it’s only partially working while other terminals don’t have this problem. . I don’t think you should tinker around on on the nvim or tmux layer, it’s clearly about how you implement opacity on windows.

That doesn’t bring any value here, the only thing that is not working as expected is Fullscreen opacity. nvim behavior is correct and intended. We won’t change the way it’s being handled now to completely incorrect behavior you want (by make transparent every content on a screen).

This works but it breaks any background color/theme of nvim, so not really a solution

There’s not point to make truecolored text transparent, that’s not how it works, so we’re handling everything correctly here. Only background should be transparent, not the entire window contents.

no it’s not disabled. you can have transparency when not in full screen and when not in nvim. example: tmux in a non full screen setting is transparent. fwiw other windows terminals/consoles can be fully transparent

I’m clearly saying that WINDOWS can disable it to gain better performance and that could be related to a fullscreen mode we’re using and us being a GPU accelerated program. In fullscreen WINDOWS can disable compositor for OpenGL apps for them to gain lower input latency, especially knowing that you’ve mentioned a flicker in other issue, which could signal a composition being disabled.

I feel like it’s related to #4072. The opacity is being disabled by Windows here, and I guess it’s for a reason, like direct scan out or we’re using a fullscreen mode that prevents compositor from taking place in fullscreen, and so the composition is being bypassed resulting in a missing transparency.

in nvim in tmux via remote host

If you’re using truecolor or setting background color to some value, it won’t work by design.

You’d likely need something like that in neovim config.
