Looks like this has been a problem since 2013. It’s weird, though… I’m having all these issues with drivers not updating with my newer version of Blender, and Kent’s tutorial from several years back doesn’t seem to have these issues. For instance, I moved on to the next part of the tutorial with toe rigging. In Kent’s video, it shows how the drivers effect it in real time. (Video 26 leg rigging, time 18:30). But for me, I have to click before I see how the driver fixes the toes. Same issue as above. I wonder if this problem never got fixed, and actually got worse with newer versions of Blender.
It wouldn’t be such as issue, but I keep thinking I have an error and trying to troubleshoot it… until I realize the drivers just aren’t painting their changes to the screen in realtime. Even after clicking update dependencies.
Someone’s error report from 2013:
