We've tested the latest version (188.8.131.528) from Q2 SP1 the same day Google Chrome was released. No problems have been found what so ever. IE8 renders as expected as well with small glitches which would probably work properly with their backwards compatibility rendering options.
Our suggestion is to test our online examples and verify if they look ok on your end, then upgrade to the latest version
of Telerik Reporting and if still having problems - send us your report in a support ticket. We would investigate the causes for these problems and advise accordingly.
All the best,
the Telerik team
