Thanks for sharing. So there is no option to change the Win key in Blender4, to use (for example) AltGr (right Alt) instead?

What happens if you remove the gaps between windows? Just guessing, but maybe the bug simply takes the gap width and uses it for the inner padding? I don’t use gaps at all and I’ve never experienced this issue. (Docs: https://i3wm.org/docs/userguide.html#gaps)

AFAIK the glibc compatibility issues were related to very outdated glibc versions. IMHO almost nobody with an old distro (Debian 10 or similar) will be using a modern IDE. I’m using Debian stable (12) which has a much newer glibc than required for remote ssh to work. Sidenote: half a year ago Microsoft even didn’t bother to inform its VS Code users that they were dropping support for old glibc when they updated their remote SSH extension :) I was one of many impacted users, because Amazon decided to use an outdated glibc in their weird Amazon Linux distro.

parcellite is a lightweight clipboard manager, I use it in i3. It has some useful features and supports basic key bindings. A more advanced one is xfce4-clipman (works standalone without Xfce, uses Gtk).

Someone already gave me the answer elsewhere. It is the “editor::Hover” action, this is the default keymap excerpt:

"context": "Editor",
    "bindings": {
      "ctrl-k ctrl-i": "editor::Hover",
...

I just had to remap it because I already use ctrl-k for something else.
