Since 1.16 update Minecraft has an issue when starting up especially on the Menu and Settings.

It seems to load something (I assume its the background video but it loads smoothly), and its causing:

• High CPU spike (95%-100%)
• Mouse lag delay
• Sound stuttering

All of these happened in the Menu, not during gameplay.

I can't click on anything, any further action will cause it to become Not Responding.

After couple of minute it will decide to give up and force close itself.

I cannot play because of this,

I don't have this issue on 1.14 version.
