I didn't use QjackCtl on openbox, but experienced issues with other
apps. The windows were not above all other windows, but they hide their
heads under the panel or they opened with most of the window left
outside the workspace and a few other problems happened, that don't
happen when using JWM.

I'd be inclined to question other aspects of your setup. I've never had any
such issues with openbox, and have been using it for many years.

Are you aware that there is a lot of customisation you can do if you delve into
the rc and menu files?


lxde with openbox is the choice the Raspberry Pi lot made for a very low powered device to be used by Linux noobs ... it behaves itself quite well and is very lightweight. I haven't seen these issues, but only sometimes run X (I usually use ssh, network sockets, gpio or triggerhappydeamon to control it ... and use ssh -X for apps which need a window to edit them, Pd patches for example).

Attached is the ~/.config/openbox/lxde-rc.xml with plenty of comments etc for reference.
