Hey,
during my first experience with my X-T2 I recognized the following (faulty) behavior today. In the moment of refocussing - after the camera released / took a photo - a white bar appears across the EVF for a very short time. I can't reproduce this behavior every time I'm refocussing. But it happens so often that it bothers me. At home I made a video by filming the EVF and the white bar / flickering. Beside the JPG I'm attaching you can take a look at the video saved as a GIF animation right here:

Did you experience the same behavior? Should I send the camera to Fujifilm?
Thank you.
