ANOMALY: use of REX.w is meaningless

Theres a weird bug i have found when closing minecraft with the button.

To reproduce:

1. In the launcher turn on “Open output log when Minecraft: Java Edition starts”

2. Open minecraft

3. Click around the menu

4. Press “Quit game”

5. Look at logs

[0x7FFCCA13AE40] ANOMALY: meaningless REX prefix used
[0x7FFCCAC3E3E4] ANOMALY: use of REX.w is meaningless (default operand size is 64)

NOTE: It only shows in log window, not log file. I still attacheed logs but it doesnt show the ANOMALY thing.

I added a file with what the copy-paste from thee log window looks like.
