Problems with my Roku channel on LT (with Grid Screen)

Question

Hi,I'm working on building a channel... I have the development working and functioning well - tested on the Roku 2 XS.  However, when I test it on a Roku LT - I run into problems when 'exiting' a video.. The problem is that the grid screen doesn't refresh properly (on exiting the video).This problem only shows up when I test it on the Roku LT - not the Roku 2 XS.Here is a link to the private channel: https://owner.roku.com/add/theDoveHere is the access code for the private channel: TD7Y4I'd appreciate any feedback or thoughts on whether this is a coding problem - or whether I need to limit this channel to Roku 2 and up??!Thanks-Michael.

It's also an issue on the Roku 1, for what it's worth.  The "fix" is to hide the grid screen prior to displaying the video screen.  I usually put up an roPosterScreen as a facade, then close the grid, then show the video screen.

Thanks for your help on this...
While the initial problem (of the grid not redrawing on vid exit/close) is resolved - I know have the problem that on my Roku XS - I get a green flash when I close the video. However, I do not have this problem on my Roku LT.
What am I doing wrong??!

screenFacade = CreateObject("roGridScreen")
							screenFacade.show()
	
							grid.Close()
		
							video.SetContent(videoclip)
							video.show()

							lastSavedPos   = 0
							statusInterval = 10 'position must change by more than this number of seconds before saving

							while true
								vidmsg = wait(0, video.GetMessagePort())
								if type(vidmsg) = "roVideoScreenEvent" then
										print "showVideoScreen | vidmsg = "; vidmsg.GetMessage() " | index = "; vidmsg.GetIndex()
									if vidmsg.isScreenClosed()
										print "Screen closed"
										exit while
									elseif vidmsg.isRequestFailed()
										print "Video request failure: "; vidmsg.GetIndex(); " " vidmsg.GetData() 	
									elseif vidmsg.isStatusMessage()
										print "status message: "; vidmsg.GetMessage()
									elseif msg.isButtonPressed()
										print "Button pressed: "; vidmsg.GetIndex(); " " vidmsg.GetData()
									elseif vidmsg.isPlaybackPosition()
										print "playback position: "; vidmsg.GetIndex()
									else
										print "Unexpected event type: "; vidmsg.GetType()
									end if
								else
									print "Unexpected message class: "; type(vidmsg)
								end if
							end while 
							screenFacade.close()

As per theEndless's suggestion - I tried closing the Grid, after launching the Facade.... however - I can't work out how to restart the Grid, when the Video closes. I tried grid.Show(), but it just crashed out.

I don't know if this is what's causing the problem, but you're using a grid screen rather than a poster screen as the facade.--Mark

Thanks Mark... I switched to a Poster Screen as the facade - but still the same problem - the green flash - when exiting/closing the video.
At the moment - I'm launching a facade, then the video... then closing the facade as the video exits....
theEndless suggested closing the grid screen as well.... if I do this - how do I relaunch it when I exit the video? Does it have to be reinitialized etc?
Any thoughts on why I get this issue on the Roku XS and not the Roku LT?
thanks -- Michael

RESOLVED!Okay... I worked out that by adding sleep(25) with the facade close did the trick... Has eliminated the flash.Thanks for the help.
