Problem with display of many elements in IE11

Hi,

After automatic Windows Updates today I am having problems to see correctly many elements in any webpage, this is more notorious in buttons, where I can always see some weird cross.

I attach some screenshots

This is very annoying for some sites where this error is everywhere, how can I fix it?

I am using Windows 8.1 x64 with Internet Explorer 11 completely updated.

Regards,

Manuel.
