PsychoPy version : v1.85.0
Standard Standalone? Y
What are you trying to achieve?:
running demos. I am looking at the two versions of the Stroop demo
Bug report
no text displays if parameter letterHeight is set to a value greater than 0.1.
However, the demos have that value set to 0.2 for the trial session.
Editing the psyexp file solves the problem. Values smaller than 0.1 behave as expected.
