UITARS-1.5B-7B Grounding error and Screenspot pro score reproduction

Hi team, we tried to reproduce the reported ScreenSpot Pro score (48) without success, we used the suggested prompt template and postprocessing, got only around 40.

Also we saw some grounding failure on some simple examples, mostly on predicted X value. This are some examples

1. Click the Open button

2. Click the "Absence" app

Could you please test on your side as well? Thank you.

No file, test, or entry point is named. Start by running the suggested prompt template and postprocessing on the two reported examples and the ScreenSpot Pro evaluation; done means documenting whether the score of 48 and the X-coordinate grounding failures can be reproduced.
