Able to reproduce this issue on Windows 10, Mac OS 10.13.5 and Ubuntu 14.04 on the reported version 66.0.3359.181 and the issue is fixed on the latest Beta 68.0.3440.25 as per the original comment. The performance monitor cpu usage numeric counter is matching the cpu usage graph Attached is the screen shot for reference. Hence adding TE verified labels as the fix is working as intended. Thanks.. |
