I need to use Xephyr to run an old application which requires 8bit color depth.
This following command works but with a problem.
Xephyr -ac -screen 800x600x8 -reset :2 &
This application I am testing has certain functions which generate new popup windows, for example showing graphs after choosing a part of the image. When the new popup window opens, it overlaps on the top left of the previous window and hide some of the images on it, but I need to see both the images and the graph in the same screen.
I have tried to start a window manager inside of the Xephyr, some of them do work such as Awesome WM but not with 8 bit color depth.
Xephyr is such a great tool, I wonder if there’s a way to solve this problem without a WM.
