background of panel gadget

[morosh]

Hello:
In the following snippet, if, in compiler options, I checked "Enable DPI aware...." or "Enable modern theme support....", the background of the panel gadget becomes white, otherwise (both unchecked) it's gray, which I prefer.
is this normal?
using PB6.20b1, W10

Code: Select all

EnableExplicit

Define Event.i, GadgetID.i

Enumeration
  #Form
  #Panel
  #Text=#Panel+100
  #String=#Text+100
  #Button=#String+100
  #Editor=#Button+100
  #Option=#Editor+100
  #Spin=#Option+100
  #Image=#Spin+100
  #Check=#Image+100
EndEnumeration


OpenWindow(0,100, 100, 800, 400, "TEST1",  #PB_Window_MinimizeGadget | #PB_Window_SizeGadget | #PB_Window_TitleBar )
PanelGadget(#Panel, 10, 10, 600, 350)

AddGadgetItem(#Panel, -1, "test1")
TextGadget(#Text,10,10,70,20,"File name:")
StringGadget(#String,80,10,250,20,"")
ButtonGadget(#Button,350,10,40,20,"File")
ButtonGadget(#Button+1,460,10,70,20,"Convert")
EditorGadget(#Editor, 10,50,500,200,#PB_Editor_ReadOnly)
AddGadgetItem(#Panel, -1, "test2")
AddGadgetItem(#Panel, -1, "test3")

CloseGadgetList()
SetGadgetState(#Panel,0)

Repeat 
  Event = WaitWindowEvent()
  GadgetID = EventGadget() ; Is it a gadget event?
  
Until Event = #PB_Event_CloseWindow

Any help is appreciated.
Edit: Compiling with PB6.04 with "Enable DPI aware..." checked, keeps background gray.
