On my Chromebook, RMS Coach glitches during playback if I drag any scrollbar. Anything I can do?
Yes! Do the following on your Chromebook:
Browse to chrome://flags
Click "Disable" under the 3rd option: Accelerated 2d Canvas.
Click RESTART NOW at the bottom of the window.
When you return to RMS Coach, playback performance while manipulating scrollbars should be dramatically improved.
