Bug#525794: Some interesting observations on maximizing behaviour
Dear KDE Maintainers,
I like to double this report: Since I updated in May the maximizing behavior
is defective with TwinView even with the newest KDE 4.2.4 packages.
But I made some observations which may help to isolate the cause for this
misbehavior:
- I have two separate plasma screens with different background images
(as Martin).
- The window list when switching windows with Alt+Tab spans (incorrectly)
between the two screens.
- KRunner is displayed correctly on the screen the mouse pointer is on.
- When switching applications to fullscreen it works correctly (for
example kaffeine or konsole), they get borderless "maximized" to
the screen where their larger part is on.
- Interestingly with activated desktop effects window drop shadows are
limited to the first screen. When a window spans both screens the part
on the first screen has a shadow, the part on the second has none.
- When using the cube effect and switching desktops the cube looks
somehow garbled: The second screen protrudes to the right on every
side of the cube. It looks somewhat like a paddle wheel. Additionally the
top and bottom caps of the cube are incomplete.
With the older working version of kwin both screens formed a unified
rectangle on each side of the cube.
So there is a basic awareness that there are two screens but this is ignored
when maximizing windows. If it succeeds to determine which different
mechanisms are used to get the monitor information when maximizing and when
switching to fullscreen it should be possible drill down this error.
With best regards and keep up the good work
Stefan
