HTML5 black screen on chrome when mobile HDR disabled

Chrome build always runs without any 3D content visible (although UMG and US stuff is visible).
Workaround: enablie mobile HDR in project rendering settings.
Tested on 4.17 and 4.18.

Also, it is worth mentioning that when starter maps are used (I tested First Person template and Third Person Template) everything runs fine, no black screen on chrome. Also everything runs fine on Firefox. But if I create new Default map, and build it, black screen error is occurring on Chrome.

Hello,

Thank you for the report. I was able to reproduce the issue on my end. I have logged the issue, which you can easily follow it’s progress by following this link: Unreal Engine Issues and Bug Tracker (UE-51923)

If you have any further questions please do not hesitate to ask.

All the Best,

This is peculiar. To understand correctly, does it render ok in Firefox even when Mobile HDR is disabled, just on Chrome disabling Mobile HDR runs in problems? And enabling Mobile HDR works on both/all browsers?
