I recently upgraded to a 49" 5120x1440 display and when I fullscreen the web browser the Plex posters are large and the slider in the right corner will not work. If I resize the browser window to half width/full height it still will not work, but I shrink it smaller to about 1/3 width/full height it will then allow the slider to work to resize the number of posters on the screen. I have tried this in Chrome and Microsoft Edge browsers.
I have seen 2 other posts related to this, but it still doesn’t appear to be fixed.
