I recently downloaded GeneratePress. Sometimes when I log in from any device my static front page (recent posts) comes up with a blank page. The header and sidebar are visible but the homepage content is blank. I can click anywhere within the blank section and it will open a post. I was going to get a screenshot but when I logged in again it was no longer blank. It is random throughout the day.
After I messaged you back I thought of this. I will do this. the first thing I did do was to deactivate WP widget because it is powered by Ajax. I thought I read something that says Ajax is not compatible with GeneratePress.
