Sprint veers right after dodge in 32:9 (5120x1440) due to black bars

Platform: PC/Steam
Resolution: 5120x1440 (32:9 ultrawide)
Description:
Tap spacebar: Dodge/roll trajectories correctly toward mouse cursor.
Hold spacebar: Starts dodge correctly, but sprint veers right. True sprint center requires mouse left of character by right black bar width, making sprinting difficult. Game has black bars on left/right for 32:9 aspect ratio.
Appears dodge/roll trajectory calculation differs from sprint (educated guess).
Expected: Sprint holds initial direction toward mouse.
Actual: Veers right post-dodge.
Steps to Reproduce:

Set resolution to 5120x1440.
Enter game (with black bars on left and right).
Position mouse forward from character.
Hold spacebar.
