Incomplete window list when alt+tab is pressed

Description Lubos Lunak 2005-12-12 15:26:31 UTC
Version:            (using KDE Devel)
Installed from:    Compiled sources

This is basically a metabugreport for all the Alt+Tab issues. It should be redone for KDE4. Check all duplicates.

To me bug 119816 seems rather narrow in scope compared to many of the bugs that make up this one.  Did you maybe mean to dupe the other way around?

Oops, yes, thanks.

Comment 18 hcoohb 2009-03-15 11:43:20 UTC
Also, it would be a good point to have an option to select whether we want to see windows of the current desktop or windows of all desktop.
Comment 19 Maciej Pilichowski 2009-03-15 12:02:31 UTC
Done.
Systemsettings -> window behaviour -> traverse windows on all desktops.
Comment 20 hcoohb 2009-03-15 12:09:40 UTC
Ok, thanks !
sorry, I had never seen this option...
But, wouldn't it be logical to have also this option on the parameters of the desktop effect used ?

Just to be clear as to what the problem is referenced in Bug 205282,
here is a screenshot of the alt-tab box in compressed mode due to lots of windows being active.

Unfortunately there are still a few problems at 4.3.95 (4.4 rc2).

With vertical "informative" layout, with many open windows the alt-tab box extends below the bottom of the screen so that items are not visible. Not as big a problem with "compact" layout since can get many more on the screen, but with it is is still possible to "overflow" the screen.

With vertical informative layout, the mouse pointer positioning is off. If the point of the cursor is below the lower half of the desired line, it select the line below. To select the desired line the wide part of the arrow has to be exactly centered on the line.

With vertical informative layout, if there are only a few items on the list (e.g.,3) selection with mouse is way off. To select any item you have to click
in the space much above any of the items. Typically you would not use the mouse in this situation but it should still work as it did in 4.3.x and 3.5.x.

I probably wouldn't use the tabular layout, but its mouse selection is also way off (e.g., click on item in right column, selects something in middle column).

Still extends below bottom of screen with many windows open. Before (kde 3.5.x) the font got smaller to accommodate a huge number of windows in the alt-tab box.

Selection with the mouse works fine now.

However, I see another problem with a more than 13 or 14 windows in the alt-tab list. If you hold down alt-tab, you can't really see the position change at all. It seems to freeze instead of continuously scrolling. This is really visible when the alt-tab list extends the entire height of the screen. 

I am at KDE 4.4.2 (Fedora 12).

Incomplete window list when alt+tab is pressed
Comment 33 Marko Dimjasevic 2010-09-04 22:03:01 UTC
KDE version: 4.5.1
Linux: 2.6.35-ARCH i686
Distro: Chakra

There is a problem in listing all the opened windows when pressing alt+tab key combination.

For example, I had 3 windows opened and alt+tab showed only two of them. Third one wasn't rendered, but could be selected by holding alt and pressing tab till it's selected. You can see it in the screenshot in comment #32 that selection box has moved below the second window in the list.

Compositing is enabled.

If I press ctrl+F9, unlike in case of alt+tab, all windows are listed.
Comment 34 Thomas Lübking 2010-09-04 23:17:47 UTC
comments #32 & #33 are bugs #249935 resp. #249173 (this is a rendering regression does actually not belong here)

Please, add the option to show switcher dialog on all monitors in multimonitor configurations.
