There is a way to make just the outline of the screen appear while dragging the window to a new location.

Would that work for you?

Here’s some code I wrote decades ago —v

 MODULE('win32')
     SystemParametersInfo( LONG uAction, LONG uParam, *? lpvParam, LONG fuWinIni ), LONG, RAW, PASCAL, DLL(TRUE), NAME('SystemParametersInfoA'),PROC
 END 

ClearFullDrag             PROCEDURE()

SPI_GETDRAGFULLWINDOWS          EQUATE(38)
SPI_SETDRAGFULLWINDOWS          EQUATE(37)
SPIF_UPDATEINIFILE              EQUATE( 1)
SPIF_SENDWININICHANGE           EQUATE( 2)

lCurrentSetting                 LONG

  CODE

     SystemParametersInfo(SPI_GETDRAGFULLWINDOWS, FALSE,  lCurrentSetting, SPIF_SENDWININICHANGE+SPIF_UPDATEINIFILE)
  if lCurrentSetting
     SystemParametersInfo(SPI_SETDRAGFULLWINDOWS, FALSE,  lCurrentSetting, SPIF_SENDWININICHANGE+SPIF_UPDATEINIFILE)
  end
