Here's a procedure to downgrade chromium. Let me know how it goes.

Chromium browser downgrade to 126

Code:

# 1. Update package list
sudo apt update

# 2. Unhold the 129 package set (all but chromium-browser should already be un-held)
sudo apt-mark unhold chromium chromium-browser chromium-common chromium-sandbox rpi-chromium-mods

# 3. Install 126 from CS repo
sudo apt -y install chromium-browser=126.0.6478.164-rpt1 chromium-browser-l10n=126.0.6478.164-rpt1 chromium-codecs-ffmpeg-extra=126.0.6478.164-rpt1 --allow-downgrades --allow-change-held-packages

# 4. Purge leftover 129 packages
sudo apt -y purge chromium rpi-chromium-mods

# 5, Autoremove unneeded packages
sudo apt autoremove

# 6. Restart
sudo reboot

Here's the before and after

Code:
