Bug ID: 315926
Summary: Some windows cannot be made visible
Classification: Unclassified
Product: kwin
Version: git master
Platform: Other
OS: Linux
Status: CONFIRMED
Severity: normal
Priority: NOR
Component: core
Assignee: kwin-bugs-null@kde.org
Reporter: kiagiadakis.george@gmail.com
I am a gentoo user, normally building all of kde from git master. For quite
some time now (~3 months I think), I hadn't upgraded KDE. Recently, however, I
decided to upgrade it to the latest git master. After the upgrade, I discovered
a serious regression in kwin.
The bug is that the windows of certain applications cannot be made visible,
ever. So far, I have noted two affected applications:
* KeepassX
* ktp-text-ui
Both applications have something in common: They normally open without a
window. Keepassx has a systray icon, which can be used to toggle the main
window. ktp-text-ui opens in the background, waiting to handle a telepathy text
channel; when that happens, it opens a window with the chat. However, this is
something that other, unaffected, applications do as well. For example,
clementine, skype and kgpg are not affected.
Switching to another window manager (I tried openbox) fixes the problem.
One other symptom: Under KDE Plasma desktop, the taskbar does not show entries
for those windows either. Under Razor-qt with kwin, however, the windows are
properly shown in the taskbar, although they are still not visible.
Disabling desktop effects does not solve the issue.
Reproducible: Always
Steps to Reproduce:
1. Install a recent kwin and kde-telepathy
2. Try to open a chat with a contact from the contact list
Actual Results:
Chat window opens in the background (according to terminal output, if you
investigate it), although it is not visible on the desktop
Expected Results:
Show the window
I am using a dual head setup with one desktop spanning on two monitors.
