I checked several AppImages, from 2025 and even from 2024. They all have the same issue. I clearly remember that the problem first arose in 2026, whereas I hadn’t had any issues with CinGG before that. Now even the older AppImages, which used to work for me, are displaying the wrong scale. So I’d say the cause was a past update to amdgpu rather than an update to CinGG. Sorry.
