Columns in beamer

Columns in beamer

I just noticed that if I use columns in a beamer presentation (which are 
BTW a great addition!), the top margin is different from when there are no 
columns. Also, when there's, say, a lot of text in one column that overruns 
it, the vertical start of the columns moves higher.

I have also no clue about how beamer works, so I'm not sure if these are 
unavoidable issues.

TIA.

(Clearly I'm working on some beamer presentations lately!)

Meant to add this PDF which shows the issue.

Those are no doubt beamer issues. You'll notice that in the first 
slide (without columns) the image is slightly larger than in the 
second and third slides. (That may in fact be Pandoc's doing, 
because AFAIK beamer doesn't scale images unless it's told to do 
so.) Beamer normally vertically centres the contents of a slide, 
so if you have more on a slide, the top margin will be smaller.

pandoc scales the image relative to the page's linewidth and textheight, so 
if beamer modifies those, that could indeed explain the changes.
