@thiago.eec: No clue about your icons, most likely a DPI thing. Try using larger icons.

Found the solution on their porting guide.

Qt 6 changes the default scale factor rounding policy from Qt::HighDpiScaleFactorRoundingPolicy::Round to Qt::HighDpiScaleFactorRoundingPolicy::PassThrough in order to track operating system DPI settings accurately. Applications that use Qt Widgets may encounter graphical glitches at non-integer scale factors, for example on Windows with a display configured for 175%. In that case, set the rounding policy to Round to restore Qt 5 behavior.

Since I use a non-integer scale factor on my windows machine, this was causing the problem. So, to correct it, i restored Qt 5 behavior setting the policy to Round:

QApplication.setHighDpiScaleFactorRoundingPolicy(QtCore.Qt.HighDpiScaleFactorRoundingPolicy.Round)
