Yes, the anti-piracy firm Entura Internationa, a company with a reputation of being a copyright troll, sent a DMCA notice to Vimeo to take down a number of videos that contained the word "Pixels" in their title. 
Working on behalf of Columbia Pictures, the company claimed that these films and videos were too similar to the 2015 Adam Sandler movie "Pixels".
Instead, however, the majority of the videos that were taken down were short films or projects that were made by independent filmmakers and creators that did not violate the copyright in any way.
In an ironic twist, however, the takedown notice also included the official trailer for the Adam Sandler film. Whoops!
Some of the videos that were hit include a video for the song Life Buoy by the band The Pixels, a 2006 short film titled "Pixels" that was produced by a non-profit NGO, and an award-winning short film by Patrick Jean that was the original inspiration for the Adam Sandler film.
