TSR does not converge while using the color grading widget

TSR (and TAA) does not converge when interacting with the color grading widget, but while keeping the mouse still. This makes it real-time previews more difficult. The expected behavior would be that TSR starts to converge as soon as the mouse stops moving (regardless if the mouse button is still pressed)

• open a blank scene with landscape
• enter r.TSR.Visualize 1 in the console to make it easier to see when TSR is not converging (the rendered image will show normal colors when TSR has not converged and grayscale when converging/converged
• add a post-process volume and change the value on the color widget under Color Grading > Global > Gain
• notice how TSR does not converge when holding the mouse still on the wheel but keeping the mouse button pressed
