Feedback Builds made with 2019.1 not working properly on dual monitors (cloned)

I updated my game project recently from 2018.3 to 2019.1.

I noticed that when I hooked up a secondary monitor to my laptop (HDMI), and set it as clone display, the builds made with 2019.1 were limited to 30 fps and pretty unstable (buggy sound, slow down, freezes ...).

I could reproduce this in an empty project with default settings. I had 2 builds (one from me and one from someone else in the community) tested on someone else's setup with the same result.

This was working properly in 2018.3. I'm using a TV, on a daily basis, as a secondary monitor to test my game.

Is anyone else having this issue ?
