Steps to Reproduce the Bug

Only occurs on JEI pages without items and only blocks. For an example, look at page 2 of JEI with default configs. Is especially apparent when switching through pages with the creative interface open. (Look at the shadow change on the block icons for the creative tabs.)

JEI Version: 15.19.0.89

Thanks for the report!
Unfortunately I am not able to reproduce the issue.

Please try updating to JEI 15.19.5.96 and uninstalling all other mods, then send me a screenshot and your client logs if you are able to reproduce the issue.
