ACR Update -> No histogram shown

Recently, I updated Adobe Camera Raw to version 18.3.1.2580. Since the update, ACR does not display a histogram. However, when using the Camera Raw filter from the latest version of Photoshop, the histogram is shown. Since I have used ACR for years with my current computer and hardware without issues (specifically, with ACR displaying the histogram as expected), I assume that the recent ACR upgrade has adversely affected the histogram display (and whatever the bug in ACR, it is not present in the PS ACR filter).

I have not tried to roll back to an earlier version of ACR.

My first thought to correct the problem was to install the latest NVidia driver (596.36; studio driver version), but it did not correct the loss of the histogram.

I also reset GPU support from within the Preferences in ACR. This too did not correct this issue.

I admit this is more of an annoyance than a ‘show-stopper’, but if anyone knows why this problem happened and, more important, how to correct it, by all means please post a reply.

Thanks, Bob
