Bug ID: 406166
Summary: taskbar icons always show on all desktops for Qt5.9.1
based application windows
Product: kde
Version: unspecified
Platform: OpenBSD Packages
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: p...@cadence.com
Target Milestone: ---
SUMMARY
On SLES11 SP4 system running KDE 4.3.5 window icons for applications based on
Qt 5.9.1 appear on the taskbar for all desktops even though both "Only show
tasks from the current desktop" and "Only show tasks from the current screen"
are selected in the Task Manager Settings.
This does not occur with a RedHat 6 system running KDE 4.3.4 running the same
Qt 5.9.1 based application.
Note that in both cases KDE is running in a VNC server. On the SuSE system I
noticed that when remote displaying to the VNC session from another display,
the problem did not occur. I compared the environment variables from both
terminal session and noted that the VNC terminal session defined VNCDESKTOP
with a value of "X". If I "unsetenv VNCDESKTOP" (I'm using csh) and start the
application then the problem no longer occurs and the window icons only show in
the taskbar of the same desktop they are in. Doing "setenv VNCDESKTOP X"
restored the wrong behavior.
This is a critical issue because our software is being blamed for this by our
customers, even though we do not set anything that I can determine would cause
this. Note that thie problem does not occur on RedHat Linux, only on SuSE
Linux (SLES). Also, note that unsetting an environment variable that I assume
should have no effect on how taskbar icons are displayed changes how they are
displayed.
