Orwell Dev-C++ TDM GCC x64 5.11 icons wrongly placed and therefore cut off in "first time configuration"

Orwell Dev-C++ TDM GCC x64 5.11 from rapps

 When you start the app for the first time after installing there is a dlg called "first time configuration"

 Observed bahvior
The icon previews in this dlg are drawn at the wrong position and therefore are cut off at the right side. Looking closer it appears to me as if the surrounding group-box is drawn to small as well?

Expected behavior
The icons should fit into that group-box and not be drawn cut off.

There is nothing logged when the dlg opens, still here is
