Eraser tool causes high CPU usage, freezes, and only erases partially on multi-monitor setup

Hello,

I am experiencing a persistent and unusual issue with the eraser tool within the "Comment" feature of Adobe Acrobat.

Problem Description:
When I try to erase handwritten lines (drawn with the Pencil tool), the eraser behaves erratically. As I drag the eraser over a line, the following happens:

The CPU usage for the Acrobat.exe process spikes dramatically.

The entire application freezes for a few seconds.

After the freeze, only a very small portion of the line I traced over is actually erased. The rest of the traced area remains untouched.

Conditions:
This issue does not happen every single time, and I have not been able to identify the exact trigger. However, it occurs very frequently when I am using a multi-monitor environment.

Diagnostics:
I have monitored the Task Manager during these events. The high CPU load is isolated to the main Acrobat.exe process. There are no corresponding spikes in GPU usage, graphics driver processes, or the Adobe CEF Helper processes. This leads me to believe the issue is not related to my graphics driver.

Has anyone else encountered this problem? Are there any known solutions or workarounds? Any help would be greatly appreciated.

Thank you.
