I have the same problem too , I solved it temporarily , set it up to “configure panel”, I lowered the value in panel size, then I introduce the value before the edit. 1366x768 video card resolution is the same as other operating systems.
I have installed om-welcome, browsing the pages next page, at the last screen I see a white page and to exit I have to click the x in the top right, how to solve it? Is it necessary to install missing packages?
Bye !
