could you make a video of the problem you are reporting. I cant reproduce the issue that you reported here.

[u-foka (ufooka)]

Hy!

Here is a video of the problem. What's happening is:
- Click on the workspace switcher icon
- Right click on the second workspace
- The decorations missing until I move one window
- Click on the workspace switcher icon
- Right click on the first workspace
- The decorations missing again

Also I found out that this happens only when I actually land on a different workspace where I started the switcher.

[Omer Akram (om26er)]

could be quite related to bug 841247 for the root cause

[u-foka (ufooka)]

I experienced bug 841247 but in my optinion these aren't related since when I miss the decorations, the window already have focus and fully usable. Also all windows missing the decorations, not only the focused one.

[Achim (ach1m)]

Not only is the decoration missing, but the window flickers very often.
If you switch to an empty workspace you also see the last window appear for a fraction of a second.

[u-foka (ufooka)]

Achim. This is a different bug (I think) appeared after the last updates.
This bug is far older :)
