frame leftover after OpenEnded trial

dolphin — Mon, 16 Feb 2026 17:25:40 GMT

Hi all,
I’m experiencing a strange graphical artifact in Inquisit 7.1.5 (Windows) after an <openended> response trial. I have two openended trials in a row, each asking for two letters. After the participant types in the response and presses the continue button, the next trial starts correctly, but a thin gray frame/border remains at the bottom of the previous button/response box area and persists across all subsequent trials (see picture — the line next to the continue button).
Does anyone know how I can resolve this issue?

Here is a minimal snippet:

<text ls_1>
/ items = ("A X A Y B X B Y C X C Y D")
/ fontStyle = ("Arial",5%)
/ position = (40%, 50%)
</text>

<text ls_2>
/ items = ("E E F G G H I I J K")
/ fontStyle = ("Arial",5%)
/ position = (40%, 50%)
</text>

<openended I1>
/ stimulusframes = [1=ls_1]
/ mask = ^[A-Za-z]{2}$
/ position = (67%,56%)
/ size = (5%,5%)
/ required = true
</openended>

<openended I2>
/ stimulusframes = [1=ls_2]
/ mask = ^[A-Za-z]{2}$
/ position = (62%,56%)
/ size = (5%,5%)
/ required = true
</openended>

<block ls>
/ trials = [1=I1; 2=I2]
</block>

<expt ls>
/ blocks = [1=block.ls]
</expt>

Not reproducing this under 7.1.6 (the latest release; Windows):

Might help to check if it's the graphics driver acting up, i.e. get the latest one from the manufacturer's site (don't use the one distributed via Windows Update).
You can also try whether including a clearScreen in /stimulusFrames helps.

[code]/ stimulusframes = [1=clearScreen, ls_2][/code]
