Hi Folks,

I've got a user who's running TumbleWeed on his own HP laptop and is
having problems with Ghosts, as he describes it.   He's using Plasma6
with X11 on an Intel Raptorlake GPU.

Basically, when he minimizes a window an unresponsive "ghost" of that
window is left on the desktop.  It doesn't respond to cursor clicks or
keystrokes.

Has anyone seen anything like this?  I don't use TW myself so can't
help very much.  I've never seen anything like it.

Here's his writeup:

Problem:

Window ghosts are complete imprints of a window which appear after it is 
minimized.
The ghost appears identical to the window, except that it does not 
interact with the
mouse or keyboard in any way.  A mouse pointer will not change in any 
way as it passes
over various features such as text fields and menus of a window ghost. 
  This includes any
aspects of the window frame, such as minimize, maximize, and close 
buttons.  All mouse
clicks on a window ghost are ignored by the ghost, and passed on to 
whatever might be
behind the ghost.  (Which can be rather dangerous!)

If the living partner of a window ghost is un-minimized, then one can 
interact with it in
the usual manner.  The ghost will exactly mimic the state of the living 
partner the next
time it is minimized.

If one switches from a virtual desktop on which ghosts appear, the 
ghosts will disappear,
and after a brief pause reappear on the new virtual desktop.

As far as I am aware, there is no exorcism.  Once a window becomes so 
haunted, it remains
so for the remainder of the X11 session.

It is unclear what causes a window to become haunted with a ghost.  It 
may be when a
window which is partially covered is minimized?

It seems to have some connection to the state of the Task Manager.  The 
arrangement of
the icons in the Task Manager defines an order on windows.  Something 
like the following
seems to be true: if a window of an application is haunted, and another 
window of the
same application which is above the haunted window is minimized, then it 
too will become
haunted.  (A more general statement which includes this one may also be 
true.)

Regards,
Lew
