Mr Lucky Posted June 5, 2019 Share Posted June 5, 2019 I just updated to 1.7 and I cannot use it as the image I'm working on now has a strange outline and looks blurry. See screenshots: 1.6.7 is OK But here you see the outline, same file opened in 1.7 Quote Link to comment Share on other sites More sharing options...
Mr Lucky Posted June 6, 2019 Author Share Posted June 6, 2019 This is a real showstopper! I have narrowed this bug down, it is caused by having a level adjustment. On 1.6.7 it looks fine. In 1.7 the levels adjustment is causing the outline to show. In 1.7 if I disable the levels then the outline disappears and looks as it does in 1.6.7 Attached is test file , also video showing toggling level on and off (with no settings altered in levels) levelstest.afphoto levels1.7-PT2.mp4 Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted June 6, 2019 Staff Share Posted June 6, 2019 Hi @Mr Lucky, Thanks. I've logged this with our developers. This seems to be caused by the Hardware Acceleration: Metal being ON. Gabe. Quote Link to comment Share on other sites More sharing options...
Mr Lucky Posted June 6, 2019 Author Share Posted June 6, 2019 OK, but I had metal on with 1.6.7 as well due to a previous bug, so I need it. Also, the preferences for 1.7 only has metal, I can't choose anything else. Quote Link to comment Share on other sites More sharing options...

Have you tried v2? If the bug is still there, I'd suggest starting a new thread in the appropriate section.

NotMyFault Posted June 26, 2023 Share Posted June 26, 2023 The levels adjustment seems to have no effect (no slider moved out of neutral position) if I delete it and create a new one, no issue are visible. What do you want to achieve with the levels adjustment ? Why are you using levels adjustment in CMYK mode for a RGB document? Adjustments on CMYK do not work the same way as in RGB, and often give unexpected results. Affinity made it possibly to play with them, but other to RGB, GREY, LAB Mode there is no clear definition how these should work in theory or practice. It is a creative playground, not a scientific tool. All in all the first question is what do you want to achieve, and is there a way to do this in Affinity correctly by other means. Adjustments in CMYK are not well defined even in theory.

I am using it to change the look of the image. 1 hour ago, NotMyFault said: Why are you using levels adjustment in CMYK mode for a RGB document? Because I just loaded the level adjustment without knowing I had to switch it to RGB. I didn't even know it would be CMYK or that it would cause problems. If it does, you'd think it would load the levels with whatever mode the document is. Anyway thanks for resolving this. I had presumed that because a staff member responded saying it was a bug that was logged by a staff member then that is what it was.

NotMyFault Posted June 26, 2023 Share Posted June 26, 2023 After more testing with V2.1.1, there are multiple bugs: with metal HW acceleration, rendering differs from no HW acceleration (original bug report) Issue affects all non-RGB color models (e.g. LAB) Even with HW accel off, there are minor rendering changes. So I was a bit wrong when blaming it on CMYK color model alone. Never the less if you change blend mode from passthrough to normal, rendering seems correct. So you can use this as workaround. Never the less once you start to adjust the sliders of the levels adjustment in CMYK mode (e.g. master), you will run into those other issues specific to CMYK. The only reasonable use case is LAB mode and changing lightness for a "manageable" effect.
