The osd-align-x=center parameter causes an issue with the mpv-gallery-view (gallery-thumbgen, contact-sheet) scripts. This problem is as follows: images showing thumbnails of a certain time section of the current video, or showing previews of other videos from the playlist, are displaced to the right, going beyond their own frames. The displaced images overlap the right frame line of their own frame and the left frame line of the neighbor on the right. The captions are also shifted to the right, being exactly in the center under the images shifted to the right. Also, the background is shifted to the left, going beyond the boundaries of the mpv window.
