Integrated terminal keeps flickering with different colors

[banana]

Greetings,

I am using Qt Creator 12.0.2 and since last week I have gotten this curious issue with the integrated terminal :
The background color of the terminal is always random and changes randomly at each click or key pressed, there's also a tool-tip on the upper left corner of the terminal that indicates "Paint: X ms", X being a number that keeps changing. Also when drag clicking in the terminal, there are red and green dotted lines displayed.

I have attached screenshots of this issue :

I've searched in the settings and in online documentation but I have not found anything and have no clue on how it started. How can I disable this ? Is this a feature that I somehow enabled with a keyboard shortcut ?

You probably have "QT_LOGGING_RULES" set somewhere. What you are seeing is "qtc.terminal.selection.debug=true" (or maybe you have enabled all debug categories)

Thank you for your answer, it was exactly that, I had just enabled some qt debug categories. I set it back to "false" and now everything is back to normal.

Thank you.
