Google translation: The size of the miniatures in the film strip can no longer be adjusted. On my MacBookPro (model year 2013) the miniatures in the film strip in their size can no longer be changed or are also cut at the top edge. does anyone know the problem?
This is a known bug acknowledged by Adobe. See here for a workaround that helps many (but not all): Lightroom: Filmstrip is covering / overlapping filter- and breadcrumb bar | Photoshop Family Customer Community . If the workaround doesn't help, try resetting LR's preferences, which has helped some (but not all): https://www.lightroomqueen.com/articles-page/how-do-i-reset-lightrooms-preferences/ .
Finally, add your me-too vote and details of your configuration to the bug report: Lightroom: Filmstrip is covering / overlapping filter- and breadcrumb bar | Photoshop Family Customer Community . That will make it a little more likely Adobe will prioritize a fix.
Nach Löschen der Einstellungen funktioniert es wieder - Danke
