Short description of error
When I set the exposure con color management the performance of tracking in motion tracking workspace editor is too slow even doing prefetch

Exact steps for others to reproduce the error
1- Open clip in motion tracking workspace
2- Set scene frames
3- Prefetch
4- Tracking some markers
5- In color Management set view transform to Standard, and exposure to 1 form a better image contrast to place markers
6- When track other marker the performace of tracking is too slow

[Based on the default startup]
