Clicking the dropdown carrot on an error row causes the dropdown to temporarily flicker open. The dropdown contents do appear to be what they should be (stack traces, etc) but they aren’t visible long enough to read. Subsequent clicks do nothing.
I was about to post the same thing. This is a very annoying issue. For some reason when I screenrecord it with shareX it sometimes magically works. I already tried clearing my cache, and tried different browsers(firefox and chrome) to no avail. Here is a video of it happening.
