Hi Hexer, Could you please check if the "Safe Frame" option is enabled in the Display section of your Preferences panel? When rendering, the Safe Frame setting is temporarily disabled, which could be causing the viewport to appear slightly zoomed in. Since you mentioned that this only happens the first time you click the Export button, we're not entirely sure if this is the cause. However, if the issue persists after disabling Safe Frame, please let us know. Thanks! Tina
