Created attachment 99352 [details] layer docker icons Some icons on the layer docker have a light color on neutral and light themes where it should be dark. The bug wasn't here on beta.
Hi, Thanks for your report. I can confirm the issue.
More exactly the bug is that lot of icons in the layer docker don't switch color until restarting krita.
I fixed a lot of theme changing stuff in 4.0. I think there are a few icons that don't switch right, but the majority should be ok now like the layers docker and animation. Closing this for now. We can open up a new one if there are specific icons that are not switching.
