neovide: keyboard is non-responsive on startup because it doesn't detect FocusGained unless I switch away (via alt-tab) first.

EDIT: ignore everything and just jump here for reproduction steps & workaround.

tl;dr: workaround is here

Describe the bug A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior: EDIT: a better/automated way is here

1. Follow the log in another terminal via $ tail -F neovide_rCURRENT.log (must be in the same directory as somefile from below)
2. Run the following from inside a qterminal: $ neovide --nosrgb --noidle --log somefile
3. observe that any keys you press have no effect inside the neovide window and the log file doesn’t notice them, ie. the log file repeats these lines only:

TRACE [neovide::window] Settings geometry PhysicalSize { width: 164, height: 56 }
TRACE [neovide::window] Inner size: PhysicalSize { width: 1476, height: 952 }

1. Now alt-tab away from neovide and notice the new log lines:

TRACE [neovide::window] Settings geometry PhysicalSize { width: 164, height: 56 }
TRACE [neovide::window] Inner size: PhysicalSize { width: 1476, height: 952 }
TRACE [neovide::window] Settings geometry PhysicalSize { width: 164, height: 56 }
TRACE [neovide::window] Inner size: PhysicalSize { width: 1476, height: 952 }
TRACE [neovide::channel_utils] neovide::bridge::ui_commands::UiCommand Parallel(FocusGained)
TRACE [neovide::redraw_scheduler] Next frame queued
TRACE [neovide::redraw_scheduler] Next frame queued
TRACE [neovide::redraw_scheduler] Next frame queued
TRACE [neovide::channel_utils] neovide::bridge::ui_commands::UiCommand Parallel(FocusLost)
TRACE [neovide::window] Settings geometry PhysicalSize { width: 164, height: 56 }
TRACE [neovide::window] Inner size: PhysicalSize { width: 1476, height: 952 }
TRACE [neovide::window] Settings geometry PhysicalSize { width: 164, height: 56 }
TRACE [neovide::window] Inner size: PhysicalSize { width: 1476, height: 952 }
TRACE [neovide::window] Settings geometry PhysicalSize { width: 164, height: 56 }
TRACE [neovide::window] Inner size: PhysicalSize { width: 1476, height: 952 }

That’s right, it finally sees a FocusGained before the FocusLost, and I think it’s due to the lack of seen FocusGained that the keyboard isn’t responsive. This kind of behaviour doesn’t happen on any other program so far. The window is focused, judging by the title bar being blue.

Expected behavior Keyboard works in neovide without the need to first alt-tab away then alt-tab back.

Screenshots See the window has focus, as far as the window manager is concerned, but neovide doesn’t seem to know that, as the keyboard is ignored:

Desktop (please complete the following information):

• OS: Linux Gentoo ~amd64
• Neovide Version 0.10.1
• Neovim Version v0.7.2

Please run neovide --log and paste the contents of the .log file created in the current directory here: Maybe later because (unrelated) I just realized that I cannot copy the text seen inside neovide with the mouse, like I could in the (n)vim that runs in the terminal(when set mouse= aka no mouse in vim, but neovide needs set mouse=a if I want to use scroll) and thus I think I can’t use neovide due to this. Well actually there is an acceptable way: https://github.com/neovide/neovide/issues/1204#issuecomment-1033911753 and since MMB paste is already working it’s quite good enough for me, thank you very much 😃 it’s actually even better because now it doesn’t also copy the spaces at the end of the lines like it would do in the terminal!
