QT,QML , Combobox's popup is opened transparent : I Have an combobox(Control 2.0). I write myown combobox like 

    	Rectangle
				{
	
					border.width: 1
					border.color: "lightsteelblue"
					height:dp(40)
					width: parent.width
	
	
					ComboBox {
						id:tmCombo
						model:combotm.datalist
						textRole: "value"
						anchors.fill: parent
						currentIndex:-1;
	
						contentItem: Text {
							leftPadding: 0
							rightPadding: tmCombo.indicator.width + tmCombo.spacing
	
							text:tmCombo.currentIndex==-1 ? "":tmCombo.model[tmCombo.currentIndex].value
							font: tmCombo.font
							horizontalAlignment: Text.AlignLeft
							verticalAlignment: Text.AlignVCenter
							elide: Text.ElideRight
						}
	
	
	
	
						onCurrentIndexChanged: {
	
							if(currentIndex!=-1)
							{
								var sqlid=model[currentIndex].sqlid;
								combotm.getsqlid(sqlid,1,Query.SelectSubParam,Query.Subq,"TMC",1);
								TaskResult.taskresult.HatBilgisi_TM=sqlid;
								tmsCombo.enabled=true;
	
	
							}
	
							else
								tmsCombo.enabled=false;
	
							tmsCombo.currentIndex=-1;
						}
	
	
				}
	
	
		}
	
My Problem is , When Combobox first open , half of popup is transparent.Then I close and open combobox again. Everthing is OK. I am working in android platform.
