SUMMARY When working with a wrapping image, you can use the Gaussian Blur filter to blur the image and preserve looping. However, when using a filter layer Gaussian Blur, looping will not work as expected. STEPS TO REPRODUCE 1. Create a layer using Open Simplex Noise with looping enabled. 2. Gaussian Blur the result using the filter operation. The edges should wrap around as intended. 3. Undo that filter and now add a Gaussian Blur Filter Layer without any mask. 4. You'll notice that this Gaussian blur introduces hard edges at canvas border, which is the unintended behavior. EXPECTED RESULT Both filters should behave the same. Perhaps wrapping around the canvas should already be a toggle as well to make the intention clear. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro 18.0.4 Illyria ADDITIONAL NOTES Bug #355865 seems to be where these two elements branched into different behavior perhaps? Seems like it'd be an easy fix.
Hey Eoin, can you still reproduce this with master? I don't seem to be able to reproduce this here on KDE Neon.

Hi, I have this bug too : the blur filter behave differently if we have the image wrapping on or off, but we don't have control on it with a Blur Filter Layer. I'm on Windows 10 64bit, version 4.2.8 (stable). The suggestion of Eoin seems good (adding a toggle to enable blur wrapping).
I'm going to go ahead and assign myself and explore this myself.
