Matrix row height misalignment

I use a giant matrix visual in my reports, instead of using cards. 
In order to get the desired verticle spacing, I use a combination of row padding, row header font size, and blank line measures.

When I publish these reports, for some users in some browsers the matrix height for each row is different leading to misalignment with my background image. For example below. The bottom image rows are slightly thinner leading to them overlapping the text.

I created published a test report, where I found that the rows were too thick. I inspected the browser elements, found the pixel heights were different, for my 2 computers, 40px per row in one and 43px in another, both were using the same version of chrome.
