Input lag/stutter when holding left-click (attack) + rapid right-click (block spam via macro) in Bedrock 1.21.132 on PC (smooth in 1.21.144)

Summary: Input lag/stutter when holding left-click (attack) + rapid right-click (block spam via macro) in Bedrock 1.21.132 on PC (smooth in 1.21.144)

Description:
Lag/stutter occurs specifically when combining manual left-click attacks with high-speed right-click spamming (e.g., Razer macro at ~15+ CPS). Game inputs delay, skip, or cause micro-stutters. Lowering mouse polling to 500Hz or adding macro delays works sometimes but also has that problem sometimes. Not seen in 1.21.144.

Steps to Reproduce:

1. Use Razer mouse at 1000Hz polling rate (Synapse > Performance).

2. Create/bind macro: Rapid right-click toggle (e.g., down 0ms delay up repeat for block place/break spam play back option: play while the assigned key is pressed).

3. Join world/server, activate macro (spam blocks).

4. Hold left mouse button to attack nearby mob/block.

5. Observe lag after 2-5 seconds.

Expected: Smooth inputs like manual clicking or in 1.21.144.
Actual: Input delay/stutter—attacks miss, blocks place erratically.

Versions:

• Minecraft: 1.21.132 (issue) vs 1.21.144 (works)

• OS: Windows 11 [your version]

• N/A (Bedrock)

• Allocations: N/A

• 
  Mouse: [Razer deathadder, Synapse version]

Notes: Reproducible without macro via manual rapid right-clicking at high polling. VSync off, settings maxed.
