Blank UI on Windows 10

[kaiserguy]

I'm trying to run SyncTrayzor on an Intel Compute Stick running Windows 10 and the UI is coming up blank. I've already tried restarting SyncTrayzor, rebooting the compute stick, and running as an admin. No dice. Works fine on my Windows 10 Dell Latitude E5540.

Might be worth mentioning that the compute stick is not currently connected to a display device. I'm remoting into it with TeamViewer. I'll try connecting it's HDMI output port to a TV and see if it behaves differently.

[kaiserguy]

Plugging the stick into the HDMI port of the TV made the difference. Now the GUI is loading just fine.

Where did you get that log from? It looks like it's from the embedded browser, but none of the stuff inside the window is loading - there's no menu bar, console, etc.

If it's working, try turning off hardware rendering in the settings, see if that improves things when it isn't connected to a display.

Hi, any response?

[canton7]

Closing as no response. I'll re-open if you respond 😄

I am having the same issue with the latest version

[canton7]

You can't see the menu bar at the top?

[jarppiko]

My window was exactly like what is shown above. The UI seemed to work, but the whole window was blank.

I managed to fix this as follows:

1. Win 10 > Settings > Display > Graphics Settings
2. Graphics Performance Setting > Classic App > Browse > Select SyncTrazor.exe
3. I selected NVIDIA GPU for the app (the laptop has two GPUs - onboard Intel and Extra NVIDIA)
4. SyncTrazor > Exit
5. Start SyncTrazor again

Might be something related to Intel GPU drivers?? I have no idea, but now it works again.

[canton7]

Interesting. The issue, whatever it is, is between your graphics card/driver, and DirectX / WPF's usage of DirectX. Either way I'm afraid there's don't think that I personally can do.

If someone else is having the same problem, disabling hardware rendering worked for me.

[canton7]

Interesting. Did you have exactly the same issue, where the menu bar wasn't shown?

[gabbe]

Well this is weird. First of all, I am 95% sure that I had the menu bar visible (sorry, should have noticed that in the original bug report). Now the weird part: to verify this, I enabled hardware rendering again and now the problem is gone. So the good news is that everything is working fine for me, the bad news is that I can't help debug the problem :)

[canton7]

Yeah, the menu bar being hidden is that makes this all the weirder. The hardware rendering option only affects the embedded browser, not any of the stuff that sits around that (such as the menu bar). Your issue sounds more like #616.
