In our scenario, all of the columns are visible at all times. There is a brief flash of the columns that aren't frozen, and then they disappear again. We do have a workaround, which is to resize the window, and that makes them reappear.
As I say, this is a bug that seems to affect Chrome when hardware acceleration is turned off,and only in certain circumstances. I haven't been able to create a project that recreates the issue either, as yet, so I think I am probably going to try and work out how to raise this as a Chrome issue as it is starting to feel more like their problem - browser rendering should be consistent with and without hardware acceleration, and this issue doesn't affect Edge, Internet Explorer or (as far as I can tell) Firefox.
