Channels Dock: RGB channels previews with alpha channel are not correctly rendered
@tmanni
Submitted by Thomas Manni Link to original bug (#776967)
Description
Created attachment 343063 Screenshot with image 640x480 and channels preview size set to Extra large
How to reproduce:
- make sure channels dock is displayed
- have a image composed of one full white layer with alpha channel full opaque
- use the eraser tool (without the antierase option) on the layer to put some alpha pixels to zero
Current behavior : not only the alpha channel preview is changed: black pixels appear on the RGB channels previews Expected behavior: RGB channels previews should not changed after the use of the eraser tool, since only the alpha channel is modified
Important detail: bug reproduction is not systematic: image size and channels previews size are involved in this unexpected behavior; so, try to use different image size and different channels previews sizes to obtain to current described behavior.
