Window width calculated incorrectly

[Nazar Mokrynskyi]

When Unity launcher is visible and I place 2 windows to occupy exactly half of the screen actual width is just a bit bigger than necessary. I can be detected when setting CCSM > Animation > Focus Animation > Dodge

If Unity launcher is hidden on located at bottom then width is calculated correctly.

Should be fairly easy to fix I guess.

Error disappears if disable gtk-window-decorator, but decorations will disappear as well.

Which release of Ubuntu are you running? We no longer use gtk-window-decorator.

[Nazar Mokrynskyi (nazar-pc)]

I'm on Ubuntu 16.10 (as of today, always have up to date dev version of Ubuntu).
I was using Unity session when filled an issue, now I have custom session with just Compiz (no Unity plugin installed at all), but still having exactly the same issue with gtk-window-decorator.

After your comment I suspect this might be a bug in Compiz. Can you reproduce an issue?

[Andrea Azzarone (azzar1)]

Not sure I understand the problem, but here are correctly sized as shown in the the screenshot.

This is not the case for me neither in my custom session with gtk-window-decorator, nor in stock Ubuntu 16.04.0.

From what I see they are correctly sized. The shadow makes it feel the focused windows is bigger.

[Nazar Mokrynskyi (nazar-pc)]

Don't you think it should be fixed? Quite annoying since I often have 1/2 or 1/4 sized windows side by side.
Also if launcher is hidden there is no issue.

[Nazar Mokrynskyi (nazar-pc)]

So don't you think this issue should be marked as Confirmed rather than Incomplete?

[Nazar Mokrynskyi (nazar-pc)]

I've disabled all of the plugins that might cause shadow, there is no shadow visible, but jumping is still present.
Can you update status from Incomplete now?
