Waveshare 4 inch LCD works on v4.2.3, not on v5.3.1

[username]

I bought a Waveshare ESP32-S3 4inch Capacitive Touch Display.

They have ESP-IDF demo code for LVGL. When I tried it with ESP-IDF v5.3.1 it works, but you can tell the LCD doesn't quite like the timing.

I reached out to them and they asked to try v5.2.3. Thought for sure there was no way this would be the issue. Yet it worked just fine.

Might anyone have an idea why v5.3.1 is causing this issue ?

Found the issue, but don't know why it breaks it.
After installing v5.3.1, and a few months later I did a git pull --recurse-submodules in my J:\ESP_5.3.1\esp\v5.3.1 folder.
Doing this causes the LCD to look funny.
I just re-installed v5.3.1 and re-built the project and it works fine now.
