Lumia 950XL - Project My Screen not working after Win10 1803 Update - Black Screen

Anonymous

I use my 950XL extensively for demos of my company's software because it's much better display than my iPhone and doesn't need additional apps to do it.

I updated my Win10 desktop today to 1803 and also my phone updated to .104 and the app no longer works.

When I open the app I get the message on the phone to ask if I want to share and I agree. The display on the desktop is black, but I can actually start applications on the phone by clicking inside the black window, so there obviously is a connection, just no display.

I was working perfectly, but not now.

As a workaround, is it possible to use continuum? I'm sure there used to be an option to display the phone's screen rather than a full desktop to the connected display but that appears to be no longer available

Thanks,

Chris

    Sorry for the late reply. It just happens. I have no idea how to reproduce. So I've recorded a gif for you.

    This time it happens at the bottom of the screen too.

    Oh, I see and it's not bug but is specification

    by original author.

    I found the following code in original source.

    * If you do LBUTTON double click, it's converted to

      SPCAE key down.

    * If you do SPACE key down, App pauses drawing.

      And you do SPACE key down again, App resumes drawing.

    I don't know why original author implements such a

    operation. (It may be for easy recording operation?)

    It's easy comment out these code.

    But should I do it or not?

    No doubt, it is the same as the problem I pointed out.

    And I can also reproduce it latest my app.

    But like you, I can not reproduce reliably and

    I cannot find any bug about touch event...

    This may be specification behavior by MS

    because it's same in MS app...

    Thanks for all your help on this.

    Have you made any more updates?

    Unfortunately mine experiences regular crashes but otherwise the functionality is exactly what I need.

    I'm glad to hear it:)

    > Have you made any more updates?

    No plan. My to do for the app are:

    * Avoid crash

       =>It's MS's matter. I can't fix it.

         We may wait next major update of Win 10;(

    * Comment out that double click => space key => toggle drawing.

       =>It's easy but should I do it or not? I wait for opinion.

    * Fix distortion of touch coodinate

       =>It may be specification. I don't know the way of fix it.

    So, I am pending these issues.
