wl-copy/wl-paste hang when used from guake

[alexheretic]

Steps to reproduce using guake on Arch

$ wl-copy foo

This hangs until I toggle guake, when I return I see it has run. Similarly for wl-paste.

This is very likely the same as https://github.com/bugaevc/wl-clipboard/issues/163, but please mention what compositor you're running this under (Mutter?).

Yep mutter.

[bugaevc]

Well, there isn't much I can do on my side here. Either Mutter needs to implement a better clipboard protocol that doesn't require me to steal focus, or Guake needs to stop preventing me from stealing focus. The former is unlikely to happen, so hope for the latter 🙂

Thanks for the info! Any idea how the latter happens? How is guake preventing this?

[alexheretic]

It looks like the guake "Stay on top" option is preventing wl-copy focus steals. Thanks for your help.

thanks for you help. I need to uncheck the "Stay on top" option to make it work.
