Visibility of Projects/Activities/Resources/etc.

Dear,
since I am not 100% sure when (I think it is since upgrade to V4.5.x) I have the phenomenon that I don't see projects, activities, etc. (please see attached screenshots).
The Filter selector for the page only appears after moving the browser window (using google chrome Version 40.0.2214.111 m).
Currently using Projeqtor V4.5.5
Maybe some settings on my side are wrong.

Thank you
Christian

Dear babynus,

thank you for the quick reply.

Clearing the browser cache has not helped. I do not have this problem in Firefox, so it might have to do with some other setting. As you can see in the first jpeg, the filter menu does not show. It seems that the loading of the page stops before complete loading. just after re-sizing from full screen to window mode, first the menu appears, then I can use the filter...
Additionally the scroll bars (vertical and horizontal) in child windows do not appear until change of window mode.

I connected to the demo site (on demo.projeqtor.org/view/main.php) and have no problems.

Can you think about any server side (php?) settings that could cause this strange behavior?

Dear babynus,
thank you for all the tips.
Now it is working. Zoom was set to 90%. After changing to 100 percent, no strange behavior any more.

Again thank you for your great and patient support!
