neovide doesn't go transparent in fullscreen in wsl

[abd0-omar]

when I open neovide and it's fullscreen it gets transparent but when I press anything the background becomes black
and the transparency is working fine when not in fullscreen mode
I don't know if the problem is a windows thing or neovide

Sorry for the late answer but are you running Neovide from within WSL or through native Windows with neovide --wsl? We only really properly support the latter.

I tested with #1977, which includes some fixes to the transparency rendering, and with neovide --wsl it works properly, also in full screen.
