Looks like arace condition ... Kwin updates first so plasma is not adjusted yet
and so the "is it the size of a screen" test fails.
I guess the question is if kwin should be trying to manage the root window at
all. Either it shouldn't touch anything or we will need a new window hint for
rootwindows which notes what screen (if any) they are associated with.
I wonder if kwin would ignore a root window that sets the wm override hint? If
so then we could leave kwin as it is anf just have plasma manage its own root
windows.

As an experiment, I applied this patch to kdebase/workspace/kwin/geometry.cpp:
@@ -993,12 +989,12 @@
{
if( isDesktop())
{
- if (geometry() == workspace()->clientArea( ScreenArea, this
))
- {
- return;
- }
+// if (geometry() == workspace()->clientArea( ScreenArea,
this ))
+// {
+// return;
+// }
- QRect area = workspace()->clientArea( FullArea, this );
+ QRect area = workspace()->clientArea( ScreenArea, this );
if( geometry() != area )
setGeometry( area );
return;
It resolved the DesktopView resizing to 3600x1200! Now, I need some
info on whether it is a correct fix or not, and if more is needed.
Cheers,
