--- Comment #4 from Noah Davis <noaha...@gmail.com> --- Right now, the expected behavior for All Screens and Rectangular Region (requires an image of all screens before making a selection) is this: With one scale factor, combine all screen images into one image with the given scale factor. Quality an image size should be accurate to what the user sees. There are a few exceptions, but those shouldn't apply to your case. With multiple scale factors, the highest scale factor rounded up to the next integer is used. This has the following benefits: - Screen images with integer scale factors remain crisp, event when fractional scaling is used on some screens. - Screen images with fractional scales should have decent quality too, but they can never be perfect. - Relative screen image positions and sizes match the relative screen positions and sizes set in the Display Configuration KCM. *Rounding up* the scale factor is not necessarily required for this. I'm mentioning it because it's important and it affects what kinds of scaling operations you can make look good. This has the following downsides: - A region screenshot entirely within a single screen is unnecessarily large. This can be improved with https://invent.kde.org/graphics/spectacle/-/merge_requests/372. - A region screenshot or all screens screenshot with multiple screens must be a larger size than the logical size. We have to make tradeoffs and trading file size for quality seemed acceptable. In my testing, there were no obvious issues with quality compared to other methods when using different combinations of fractional scales or integer scales. -- You are receiving this mail because: You are watching all bug changes.
