Qt4/KDE4 software under 10.14

[Richard L. Hamilton]

I wonder if the flashing isn't a rendering issue similar to what MacVim is having, where the behavior of a legacy rendering technique changed?

At least in my testing, PyQt4 has some display glitches that make it challenging to use: the Qt4-based windows flash a lot, and at random times. Doesn't matter dark or light mode. Note that MacPorts' PyQt4 is not at the latest version (due to major compatibility issues with it and current ports) -- so there might be some fixes already in place for this way of using Qt4.
