I do aknowledge some of my PNG are wayyy too big, but even after resizing all I could to be less than 1000x1000 pixels this is still happening > What version of the product are you using? Is it "nightly build"? Which operating system do you have? Happened both on latest github commit and last stable release. Operating System is EndeavourOS, but also happened on the latest Ubuntu LTS on github actions. > Please provide any additional information below.
