Captured screenshot for frame xxx

[dkl3]

Hi, whenever i try and take a screenshot, this message of "Captures screenshot for frame [number]" appears in the screenshot, unless the text fades off screen. how do we fix this? this happens if i push f12 a few times, which tend to do if i want to get the right frame at the right moment.

additionally, is there a way to change which button to press if you want to capture a photo? i may want to map that to controler
