Builder key response start/stop times recorded incorrectly

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Win 10
PsychoPy version (e.g. 1.84.x): 2021.1.4
Standard Standalone? (y/n) If not then what?:y
What are you trying to achieve?:
Present a text stimulus from 0.05sec
Take key response from: 0.5-1.25sec
Have the start and stop times of the key response period recorded in the csv.
What did you try to make it work?:
Ran the experiment. The code is the default built by the builder, I made no customizations.

What specifically went wrong when you tried that?:
Include pasted full error message if possible. “That didn’t work” is not enough information.

Here are the relevant columns of the csv

key_resp.keys key_resp.started key_resp.stopped
None 20.9945972 None
None 23.4141408 None
None 25.9142052 None

Are you noticing any delays between trials? It looks like there’s something holding up the experiment for approx 2 seconds after each trial, is there anything else your experiment is doing besides the keyboard?

There are no delays between trials. The only elements in the trial routine is a textstim followed by a key response.

I tried a way of getting around the problem by adding a 0.01s ISI after the key_resp and it worked. This does solve the issue but it does cut the key response short by a little.
