Hello, first of all I apologize for my English, I am not a native english speaker.

Since the 1.14.30 on Bedrock Edition I encounter light issues on blocks every time I am mining a block or when I add a light source.
It seems that the game fails to update the light value on several block around me each time I break a block or when I put a block which produces light.
It lasts less than a second. It is like a flash. So when I play it is like I am starring at strobe light.

Here is what I tried to solve the issue, without success unfortunately:
-Uninstall/Reinstall the game.
-Play with and without Resource pack.
-Change ingame graphic settings one by one.
-Change every value of the game one by one in the 3D settings of the Nvidia control panel.

Here is the specs of my potatoe:
Windows 10 Family
Intel core i3
Nvidia Gforce GT 520M
4GB of Ram

My Drivers are up-to-date, and my windows 10 version is the 1909
