Description Raman Gupta 2015-12-14 23:07:09 UTC
The system activity manager opens partially off-screen. I have a multi-monitor setup with 3 screens. The two left and right screens are smaller and centered off the middle screen. The default screen is the middle screen. The system activity manager opens partially visible on the left screen. After it is moved and closed, it does not remember the previous position (and kwin rules to that affect do not work).

Reproducible: Always

Steps to Reproduce:
1. Open System Activity

Actual Results:  
Displays partially off-screen

Expected Results:  
Should display completely on-screen

This installation is upgraded from KDE4.

Gentoo, Plasma 5.8.3

I have a dual screen setup, systemmonitor always opens up on a secondary screen, seems to be related bug?

In my case offending line is geometry setting in KSystemActivityDialog::slotInit that disregards that geometry can have x1,y1 > 0 for multi screen setups
Comment 2 Raman Gupta 2016-11-24 15:01:56 UTC
Still happens in 5.7.5, QT 5.6.1.
Comment 3 Raman Gupta 2016-12-01 13:54:42 UTC
Still happening on Plasma 5.8.4, QT 5.6.2.

I think it is the same issue. If the screen opened on my main center monitor, it would be the correct size and position within that monitor. However, it opens on the wrong monitor.

It seems as if KDE is using the correct monitor to calculate the window's size and x,y position (relative to that monitor), but then actually placing the window on the wrong monitor.

Screenshots please.

Please also run "xprop" from a terminal and click on the window.

Then reset the bug status to unconfirmed.

Screenshot of window just after it opens via ksnapshot. Note its location on the left monitor, which is smaller than the center and right monitors.

Center systemmonitor window properly on multi-screen setup

Do not force geometry or window hints when opening systemmonitor
This should let it position properly on a multi-monitor setup and reduce interference with user-set KWin preferences
