When in the "Shading" workspace and I am adjusting shader node values, the viewport will not start to render. It will go through updating the shaders, render, and then it gets stuck on "Waiting for image...". I have waited for several minutes to see if it will start to render, but doesn't. It will only start if I rotate the view a little, then it renders normally.
It will also start to render normally if I connect or disconnect a node.
