Chromium first run is always wrong

[monobot]

I have a strange problem with my chromium browser, never happened before in other linux desktops

Everytime i start chromium after a reboot it comes in a different screen resolution thus its seen very small and also i cant clic on the tabs. I cant maximize because for the program its in its maximum size.
After i close it and/or start any other instance of the browser everything is ok.
Any clue of what is happening?

That only happens to chromium btw.

This is a screenshot:

I had the same thing just yesterday, for the first and only time so far, also with Chrome. Also Nadia + Cinammon + ATI GPU

Update, today the browser started with the same behaviour.
But then when i run a second instance of it never started again, i had to uninstall and install it again.

Any1 has a clue about it? thanks in advance

No clue, but today it happened to me with LibreOffice Writer. Not consistently reproduceable though...
