// The situation with wxProgressDialog is quite interesting here.
// On Linux (only), there are issues when FDM/SLA is switched during project file loading (disabling of controls,
// see a comment below). This can be bypassed by creating the wxProgressDialog on heap and destroying it
// when loading a project file. However, creating the dialog on heap causes issues on macOS, where it does not
// appear at all. Therefore, we create the dialog on stack on Win and macOS, and on heap on Linux, which
// is the only system that needed the workarounds in the first place.
