Our screens are positioned by tables, that limits it positioning, they are not enough dynamic.
To make it more advanced, it needs to be redesigned and code should be rewritten to use divs.

P.S. Currently we leave to decide how to position up to browsers inner constructions.

as relying on browsers to layout screen correctly is sub-optimal, this issue might serve as the beginning point for screen redesign

Still seems to be an issue in pre-3.0.0beta2 (trunk) r57901.

Slightly related feature request: ZBXNEXT-3113.

with patch attached to ZBXNEXT-3113 corrected screen will appears automatically (result presented on 2016-01-25_17-14-08_1690x1001.png screenshot)

Thanks for the patch, baya! However, on "2016-01-25_17-14-08_1690x1001.png" the lower right graph should span two columns, not one. Also, please attach a screenshot with a smaller size.

This is very old bug (on most browsers). They rearrange spanned columns in nonunderstandable manner. To avoid it we should initialize all cells in table with width "1px".

Also I add some speed optimization at patch in ZBXNEXT-3113.

Not actual for latest versions starting from 5.4. Screens and templated screens was completely replaced by dashboards.
