Description Aleix Pol 2014-04-10 15:41:14 UTC

If I maximize on a system where there are 2 screens with different resolution, I get the window maximized to the smaller resolution although the whole desktop is being set up in the bigger screen.

I'm attaching an image so that it makes more sense what I mean.

Reproducible: Always

I'm using a similar setup in daily productive work and don't have such issues.

A few things to try:
* is that also happening with non-Chromium windows?
* how does it look if you kill plasma?

seems a cloned/overlapping setup - can't test atm, but the maximize area will be calculated for the "wrong" screen.

what if you move the unmaximized window so that 50% are on the non-overlapping region of the bigger screen?

Comment 4 Aleix Pol 2014-04-10 16:54:09 UTC

Martin:
- It does happen with konsole and systemsettings too. On the other hand, I must say that depending on where the screen is, it uses the bigger size.
- Same thing happens without a plasma

Thomas:
- Yes, it seems to use the correct size

Comment 5 Thomas Lübking 2014-04-10 18:54:27 UTC

Raises the question why a client would reasonably be considered on fully included screens.

- wanted partial maximization (poor mans tiling: "i keep my toolwindows on the free part"; projector case: "demo on both, text on mine only")
- impact on currect screen estimation (where do new windows popup and does one really want to restrict that area / maximum size?)

An alternative solution might be two-step maximization (maximize - maximize more - restore)

Comment 6 Thomas Lübking 2014-04-12 19:13:11 UTC

btw, the bigger screen is the secondary one, right?
Tried making it the primary?
