Sadly this is not something we have great test coverage for. 753833 3 jamesr 2012-10-29 16:13:22 -0700 Seems to do the trick. Perf #s from my linux box (where slower-than-average texture upload speeds are having a disproportionately bad impact on threaded mode perf), all average of 3 runs: moz software: 6014 moz FCM: 6295 (4.7% slower than software) moz FCM threaded unpatched: 7535 (25.3% slower than software) moz FCM threaded with this patch: 6359 (5.7% slower than software) intl1 software: 27035 intl1 FCM: 28458 (5.3% slower than software) intl1 FCM threaded unpatched: 41045 (51.8% slower than software) intl1 FCM threaded with this patch: 29382 (8.7% slower than software) 753839 4 171320 enne 2012-10-29 16:17:23 -0700 Comment on attachment 171320 Patch R=me.
