Time bar disappearing while giving play on preview of the vocals

I do not know if this is really a bug but it’s something that should not happen, basically what happens is that the http://prntscr.com/lzif8n (print) timeline adds up to give play a preview of the vocals.

I am using the following equipment: https://www.3dmark.com/3dm/26820006 (but using the most up-to-date version of windows)

OS: Windows 10 pro for workstation
CPU: Xeon E5-2670v1
GPU: RX 550 4Gb
RAM 6Gb 1333mhz

I have this issue too although mine blinks more rapidly

Same issue but mine blinks more rapidly.

I have the same issue but if you activate this option then it won’t happen, maybe.

Although I couldn’t replicate the issue on my devices, this bug has been marked confirmed due to multiple reports of incidents.
I’m mostly sure about the cause though. For more speedy response and fluid experience, in the current release the playhead’s refresh rate has been set to 60 Hz which might be too fast for the graphics to render (or it coincides with your monitor’s update rate). Guess we’ll add an option to slow it down.

Added to Build 013 release plan.
