YouTube appears to be testing larger thumbnails on its desktop site, much to the chagrin of select users who balked at the changes as soon as they started rolling out yesterday.

Screenshots of the experiment began appearing on Twitter and Reddit yesterday morning, per The Verge. Accordingly, homepages that were part of the test saw videos that were no longer grouped by category, and with fewer appearin in each row. YouTube confirmed to The Verge that it is “currently testing a new homepage layout to improve the watch experience for our users.”

However, some felt the changes had precisely the opposite effect, complaining that the larger thumbnails made it difficult to scroll through the homepage, and also caused a disorganized and disorienting effect.
