--- Comment #2 from [email protected] --- (In reply to pawlowski486 from comment #1) > Hi, I think I am experiencing the same problem. I'm using Krita Portable for > Windows, version 5.2.15 > This issue does not seem limited to the "eraser" brush tool, it also applies > when using the Elliptical Selection Tool to cut and paste parts of an image > between layers. > > STEPS TO REPRODUCE: > 1. Open a JPEG image stored on the computer as a new image. > 2. use the Elliptical Selection Tool to select a circular part of the image. > 3. Cut out the circle by hitting Ctrl+X. > 4. Paste the image with Ctrl+V. This will automatically create a new raster > layer. > 5. Right click the **original layer** and choose "Remove Layer", this will > leave you with a circular image with transparency around it. > 6. Save the image as a .PNG. (settings are Compression 9, Interlacing on, > Save as HDR off, Embed sRGB profile on, Force convert to sRGB on, Store > alpha channel (transparency) on, Store Metadata off, Sign with author data > off, and Force convert to 8 bits/channel off.

I agree with madmrmax that this seems to be an issue > of Krita setting the alpha channel to zero when it should really be setting > all channels to zero.

Correction, that was the "Eraser Circle brush tool"; there is no such thing as an "Eraser Brush brush tool" built into Krita. -- You are receiving this mail because: You are watching all bug changes.
