Roly Poly Goblinoli Posted December 28, 2017 Share Posted December 28, 2017 (edited) Specs Paint.net version 4.0.19 running on Windows 10 64-bit Home edition Problem Transparency of all pixels in paint.net's canvas is sometimes displayed at a higher opacity than the actual opacity of the image. This occurs intermittently at random when changing the zoom level, and no particular zoom percentage always displays this bug. If you take actions on the image, the transparency reverts to normal. Rectangle select refreshes the pixels under the rectangle you draw so those pixels display as normal. This leads me to believe this is a redrawing problem. Steps to Reproduce 1) Open paint.net. 2) Set the primary color to black at 121 alpha. That's what I tested at. 3) Use the fill bucket to fill the screen with that color. 4) Zoom in and out until the bug occurs. Though this bug occurs randomly, it does so at high frequency, so only a couple times zooming in and out should do it. You don't need to zoom to max or min.

Rick Brewster Posted December 28, 2017 Share Posted December 28, 2017 I've known of this issue for quite awhile but haven't taken the time to investigate it yet. It's been around since 4.0 (mid-2014). This seems like a good time to debug this -- I've been fixing a whole bunch of little leftover bugs for the 4.0.20 update Thanks for the writeup!

Roly Poly Goblinoli Posted December 28, 2017 Author Share Posted December 28, 2017 (edited) Sure thing Rick. To be honest, I've known about it since early 2016, but I didn't post about it until just now. Like that other bug I submitted and said I knew about for three years . Hopefully I remember to post more often when I encounter these little inconsistencies. Edited December 28, 2017 by Joshua Lamusga Quote Link to comment Share on other sites More sharing options...

Rick Brewster Posted September 25, 2018 Share Posted September 25, 2018 The double ("dark") alpha is fixed for the upcoming 4.1.2 release I had to write some custom pixel shaders but they were pretty easy (the rest of the code to integrate it was more problematic...) It's now possible for me to have fixed this because of the upgrade to Direct2D 1.1 that I did for the Paint.NET 4.1 release (see also: https://blog.getpaint.net/2018/04/01/paint-net-4-0-22-and-windows-7-platform-update/ ).
