Multiple CV tricks could help in improving OCR speed/accuracy:
- Only call OCR for regions that contain text
- Pre-process images to increase contrast and remove compression artifacts
- Some advanced thresholding based on different types of screenshots
In general we need to define metrics on general performance to identify which areas need to be worked on the most

Only calling OCR for regions that contain text did not improve performance at all. It even hurted it a bit.
