We had a very similar issue with Cognos 11.0.8 using Chrome this last summer. Opening or running a report, or Report Studio, would sometimes error out and it was annoying as all hell. We'd have to clear cache/cookies/history sometimes several times before Cognos would load a screen correctly. We dont license directly from IBM so we went through our technology partner, but even they didnt know what changed (even more stranger is our environment is on premise and rarely patched/updated). We were told to update Cognos to the next minor release 11.0.12 to hopefully resolve it. Had it in test environment and before we put it into production the issue was gone in our old environment in production. So we didnt bother with the minor upgrade in production after all. We've been Chrome-issue free for a couple months now. Still upgrading to 11.1.6 soon... so fingers crossed!
