Summary: _NET_WM_ICON hint doesn't force using icon of 'most
appropriate' size
Product: kwin
Version: unspecified
Platform: SuSE RPMs
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
AssignedTo: kwin kde org
ReportedBy: hail pochtamt ru
Version: (using KDE KDE 3.4.3)
Installed from: SuSE RPMs
OS: Linux
The following testcase helps to reproduce the issue. It specifies _NET_WM_ICON hint \
with two icons (16x16 and 32x32). The icon (16x16) is set on the window's title bar. \
And the same icon (16x16) is used in window list when switching to another \
application by pressing Alt-Tab. However, it seems like the icon (32x32) is more \
appropriate for second case (Alt-tab).
Other WMs (e.g. Metacity) use 32x32 icon in case of Alt-tab.
