The icons in Salesforce report buttons are missing in Chrome, since several months now.

This somewhat related known issue Some icons disappear in Chrome 84 is "In review" and even though the related chromium issue is supposed "Fixed/Closed", the issue persists on newer Chrome version.

Chrome version 91.0.4472.101 (Windows 10 / 64-bit)

Found quite a lot of errors in Chrome console when viewing the report, just posting a sample extract here:

Anyone having same issue on Chrome ? Any workaround ?

Works fine when viewing report in Firefox - version 89.0 (64-bit)
