Jules, I’ve been getting a lot of X errors that I couldn’t track down, then I noticed that they’re barely there in my Release build. I looked more closely, and it looks like there’s a strong, but not 100% correlation between DBG calls and the error, which is:
Error: X returned BadMatch (invalid parameter attributes) for Operation Unknown
Now these are my threads using Juce::Thread, and they’re doing X work using a separate X display connection.
Is the DBG code in the end doing anything that could trigger it?
