I am using
TeXstudio 2.6.2 (SVN 4111)
Using Qt Version 4.7.4, compiled with Qt 4.7.4 D
on Linux, with the embedded viewer. I don't if there is a bug or some other reasons but the option Fit to Window does not work so well.
When I press its button the zoom changes but always there is the scrolling bar so that is possible to scroll the page.
I guess that the problem is related with the gray strip below the page area.

You seem to have CSS turned off.
