When viewing cards on a page which uses alternating row colors (e.g. inventory), the background colors of selected rows (rows where the check box is checked) only change on rows with white backgrounds. Rows with light blue backgrounds do not change their background colors when selected.

Following is a screenshot comparison of the issue.

This is how rows look when not selected (no issues):


And this is how the first two rows look when selected (notice that the second row has the same background color as it did in the first screenshot):


This makes it hard to see at-a-glance when rows with blue backgrounds are selected (but I assume this is just a bug/oversight).
