Hi
We upgrade to NoesisGUI from 3.0.12 to 3.1.0, some UI backgroud with alpha not the same as before. We using Ogre as the render engine with linear color space. We have some test using the Login sample app.
We can see that a little deffient between 3.0.12 and 3.1.0 with linear color space
3.0.12 RenderContext::Init with sRgb=false 3.0.12 RenderContext::Init with sRgb=true 3.1.0 RenderContext::Init with sRgb=true Here is the Login MainWindow.xmal we modified.

In 3.1 we fixed #2044 because linear colors were not correct in 3.0 as we were using 8-bits to store each component and at least 10-bits are needed to encode linear colors. So it is normal if you observe "minor" differences in 3.1.

To make sure everything is correct, please, disable alpha blending and check if the color is exactly the same in linear and non-linear.

if background color with no alpha 3.1.0 is the same as 3.0.12

What about the comparison of 3.1-Linear vs 3.1-Non_Linear with alpha blending disabled.

I am reviewing the changes applied to 3.1 and I am observing something that I am not sure is correct. Could you please create a ticket?

PS: I can confirm there is a bug when linear rendering is enabled and premultiply-alpha is applied.

We set the backgroud color FFFFFFFF, login boarder background color 80FF0000, we got this. Using color picker from the screen shot we found that the 3.1.0 version login board background color is DCBBBB and 3.0.12 is FFBBBB.

Ticket created #2085. Thanks

Thank you! Planned for 3.1.1

Hi,
