SUMMARY I've had a 'Blur' via Filter layer producing white/transparent edges when I opened my file. It didn't happen before while I was doing the art. The only thing to make the white edges disappear is when I create a new layer and delete the new layer. It happens everytime when I open my file and I need to do this whenever I open the file just to remove that white/transparent edges. STEPS TO REPRODUCE 1. I opened my krita file that has a Blur filter layer 2. It automatically has the white edges upon opening 3. Creating a new layer and deleting the new layer makes the white/transparent edges disappear. OBSERVED RESULT The white edges on Blur filter layer only appears if you open the file. No matter how many times you open it, the white edges are still there unless I do create a new layer and delete the new layer to make the white edges disappear. EXPECTED RESULT Shouldn't be happening since this has never occurred to me on version 4.2.2 SOFTWARE/OS VERSIONS Windows: Windows 10 Home macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION I've added a google drive link to the video showing the bug. This keeps happening every time I open the file with a 'Blur' Filter layer. Please check the video here: https://drive.google.com/open?id=1vXLzg2dA5tl6vu8Y1Y1s7xQk7yWgOJED It's larger than 4mb, that's why I can't attach it here.
You have a multi-group, multi-layer file there. Can you simplify the situation and use just one image layer and a filter mask to see if it still happens? (It seems to be a Filter Mask, not a Filter Layer.) Does this happen with any other files you have? Does it happen if you go back to using 4.2.2 with this file?

Surprisingly, it doesn't happen on the one you suggested even when it's inside a group or opened in 4.2.2. It only happens on my file shown in the video. Tt happens when I create a NEW FILTER LAYER, not a Filter mask. I've tried opening it up on 4.2.2. The edges are there, and disappears when I hide/unhide the filter layer. New update: I installed 4.2.3 after uninstalling 4.2.2. The edges now disappear when I hide/unhide the filter layer, similar to 4.2.2. This didn't happen on the first video using 4.2.3 Here are the 2 videos showing the bug. I've also attached the .kra file showing the problem and the one that isn't. https://drive.google.com/open?id=1CrpDIzGWOJiXz-2dTKVi4l0uBx7L4ad2
Thank you for the original .kra file. Your image content size seems to be different from the image size. (This sounds strange but it's the only way I can try to describe it). If I do Image -> Trim To Image Size, the white border no longer happens on opening the file. Did you make a small change to the canvas size at any stage? [Before I noticed that, I noted that you have the Copy blending mode used for the Blur Filter Layer. If that mode is set to Normal, then the white boundary effect does not happen. This can't be the only reason because your other .kra file also has its Blur Filter Layer set to Copy blending mode and does not show the white border effect. - I'll leave the explanation for that to someone who knows about the details of blending modes.]

I tried to do the Image -> Trim To Image size. It fixed the problem, even if the filter layer's blending mode is set to Copy. >Did you make a small change to > the canvas size at any stage? Yes, I've only did once, when I was still in sketching phase where I cropped the canvas. Is there an explanation how the trimming stopped this problem? Thank you for also the new insight on the Trimming part. I might do that in the future in case something like this happens.
There are probably many interacting effects here but the main thing is that your image size and canvas size seem to be not identical in some way. There may also be off canvas content affecting things but I didn't try to find it. I'll set this bug report to Resolved - Not A Bug but you can reopen it by changing its status in the future if you have similar or related problems.
