Mac 12,1 (Non-Metal AMD) - Invisible Text Selection in Word 365 (v16.88)

iMac 12,1 (Non-Metal AMD) - Invisible Text Selection in Word 365 (v16.88)

Hi, I am using an iMac 12,1 (Mid-2011) with the original non-Metal AMD GPU, running Monterey 12.7.6 via OCLP.

The issue: In Word 365 (v16.88), text selection is invisible. The highlight only flickers for a split second when I scroll or move the cursor, but then it disappears. Everything else in the UI works fine.

What I've already tried:

• defaults write com.microsoft.Word DisableHardwareAcceleration -bool true (No effect).
• Changing macOS Highlight colors and Office Themes.
• Older versions (16.10) had the same issue.

Is there any specific OCLP Root Patch or Terminal command that can force software rendering for the selection layer in Word on legacy AMD GPUs? I really need this for my PhD dissertation.
