If you have trouble with ShowModal, then it is a bug in the LCL gtk2 
interface or below.
ShowModal had in the past some problems with other window managers
too.
Please update to 40085, compile with -dVerboseTransient, then run again.
When it happens again look at the end of the output for 'DEFINE
transient'.
