Black screen instead of image

[MalteMatthey]

Hi everyone,

I've been casting my dashboards to Google Nest Hubs, and most of the time, the background images load correctly from my img_source folder. However, after adding more images to the folder, I've noticed that around 5% of the time, the Current image is null (can be seen when debug is on), resulting in a black screen.

I haven't been able to identify any pattern or find any information about why or when this issue occurs. All of my background images are small JPEG files (under 256KB).

Has anyone else experienced this issue or have any insights into what might be causing it?

Same for me. This started after the recent updates.

I have a similar issue, the image loads but as soon as I move the mouse over the image it turns black (using Chrome on ChromeOS), and the image also fails to load on Android (Android 15 Beta).

same issue for me

@j-a-n do you have any idea what might be causing that? The issue is still persisting, and I can't identify any pattern or reason for its occurrence. I can help with logs, if needed.

Sorry, I currently do not have a Chromecast device to test the dashboard casting.

I am seeing the same behavior... I have done everything I can to ensure it isn't related to the source/storage on the local network (eliminated any/all possible bottle necks or unnecessary hops for the sake of troubleshooting this) and can't seem to get it to stop. I would say the 5% estimate is getting worse, and my number of images is low (50). Right now just living with occasional black backgrounds isn't the end of the world but it does seem to be getting worse in time.

I have an android tablet I want to use as a wallpanel. I get the same issue. The background works on my Mac and in iOS devices, but on my Android Tablet it shows a black screen with a broken image icon in the top left corner.

I had same issue solved with power cycle.

@MalteMatthey @j-a-n and others having this issue on the Google Nest Hubs, I have found the culprit on this.

This only happens on my devices which are Google Nest Hubs (I have Hub Max but it seems to do the same on others). It happens when an image is vertically oriented, and you have the background set to 'image' instead of the default 'color'. I believe the Hub devices are very underpowered (at least for this purpose) and when it has to scale a vertical skinny image up to fill the entire width, it has some kind of memory issue and won't display anything at all until the next picture comes and saves it by making the background fill 'easier'. I find that some of my vertical orientation images work but the ones that are very skinny are the ones causing the issue.

My workaround has been to either re-crop the image so it's closer to square dimensions (or horizontal), or set the background mode to color instead of image. I have had zero issues with this ever since (and now I am seeing some images that never appeared on there before, because of this issue).

I think it is more of an issue with the device than the code/project.
