New Windows app launch issue

Server Version#: 1.16.5.1488
Player Version#: 1.0.0.792

I’m having an issue launching the new Plex app for Windows. It worked okay last night and again tonight. Now when I try to launch the app, it comes up as Plex (Not Responding) with a blank white screen and I have to use task manager to shut it down. The only way to get it going again is to uninstall, delete the appdata\local\plex folder, and reinstall and set it up again. Then the problem starts again. Never had this issue with Plex Media Player and the web client and all other apps continue to work fine. Any idea what could cause the issue?
I am using Windows 10 18362.295.

Quick update. The problem seems to only occur when Plex is used on my 2nd monitor and I shut down the app and try to relaunch it again. If I keep it on my primary monitor, it does not seem to give the issue. Also to temporarily fix the issue, I don’t need to reinstall the app. Deleting the appdata/local/plex folder and signing in again is adequate. Then it appears I can drag it to the 2nd monitor as long as I remember to drag it back to the primary one before shutting down the app. Very strange behavior. Never had the issue with PMP.

Which type of graphics hardware / display adapter is used in your computer?

Do you have both a CPU-embedded display adapter and an additional graphics card?

NVidia GeForce GTX 1060 3GB (Asus).
No, it’s one of the original Intel Skylake CPUs with no embedded graphics.

Weird. I have a nVidia card as well (although a newer one).
Are you using the video card driver manually downloaded from the nVidia website or did you rely on Windows’ Update to install the drivers?
If the latter, try and download manually from nVidia.

No, I’m using the latest driver from nVidia, 431.60. I don’t have any problems with any other apps on the second monitor, only the new Plex windows app. PMP worked fine. Perhaps the problem is specific to the GTX 1060 or there is something else about my configuration the app does not like. I don’t know. I’ll let you know if I figure anything else out but in the meantime, please report the possible bug.

I have the same problem with a RTX 2080 Ti with 3 connected screens. Windows 10 1903

Same problem here.
RTX 2080, 431.60 DCH driver, Windows 10 1903, 3 * 2560*1440 displays.
Whenever I manually enter windowX=value with values greater than 1311 or lower than -1248 in the plex.ini file the App will start with a not-responding whitescreen.
Seemingly the allowed values are related to the screen resolution as the range -1248 to 1311 equals 2560 possible values.

Another workaround would be to set the plex.ini file as read-only after the first working setup.
Even after moving it to another display and then closing it will retain its startup position.
Just remember to remove the read-only flag once this is fixed.

Default path to the .ini file:
C:\Users%username%\AppData\Local\Plex\plex.ini

For what it’s worth, I have 2 displays, and 1 additional connection for my VR headset for a total of 3. I wonder if the problem is related to 3 items being connected to the nVidia display adapter.

In any case, thank you Delefant for the workaround. I have set plex.ini to read-only for now so now every time I open it, it opens on the primary monitor so I can move it after. It’s not perfect but it works for now without worrying about the white non-responding screen.

I can confirm the same behavior.

Two screen setup with a 2080ti. Plex on 2nd monitor starts up just white. Editing plex.ini so the window starts at display1 fixes problem.

Newest nvidia driver: 431.60
Win10 1903 18362.295

OK, same issue here - and the plex.ini workaround works (thanks!). Just changed windowX from 1920 (2nd monitor) to 0 (1st monitor), and no longer the white screen of death … :-).

Thanks for figuring out the repro/workaround. I’ve filed an issue to look into this.

Hi there,

This is my .ini file what would you suggest I change here?

[ui]
keepOnTop=0
windowX=228
windowY=260
windowHeight=720
windowWidth=1280
screen=\\.\DISPLAY4

.When I run Plex it comes up with the empty white screen on monitor 2

cheers

Odd that causes issues - but try setting windowX to 0 perhaps?

I have 3 monitors and a few custom apps that deal with wallpapers. Over the years, I’ve come to understand that windows reassigns the “display” id for monitors in a way that does not guarantee that the identification will be the same between sessions.

That being said, I found that simply commenting out the line:

screen=<whatever>

in the ini file and restarting the app will cause the Plex software to properly identify the main monitor.

Thank you so much! I can finally try out the Windows app!

I’m relatively new to Plex and commenting out that line finally looks as though I will be able to sign in. Before applying this fix, absolutely nothing would show on any screen. I would only have the Plex icon in my taskbar, which showed a blank preview when hovered over, but not window would ever be visible.
