Hi,

what GPU do you have?

And is there an other GPU intensive application running at the same time?

Best regards,
Klaus

No other apps running.
Lenovo laptop with Quadro K2000M - 2GB DDR3.
I commented all pictures, video layers and even hotspots, but I had to finish the project manualy.
Find coordinates of resting hotspots by trial and error.

Never happened to me in the past. I work with 1.20.5.

Here is the result:http://devetsil.ghmp.cz/

Hi,

you could try using the 32bit version of the krpano Tools application.
That one uses a different NWJS/Chromium version as GUI framework, maybe that can help here...

Additionally or alternatively you could try manually setting a smaller memory setting
https://krpano.com/docu/xml/#memory

E.g.

Source code

 
1

<memory maxmem="400" devices="desktop" />


That might be able to help, but normally that shouldn't be necessary...
I think the core problem would be more between the NWJS framework and your GPU drivers...

Best regards,
Klaus

It happens to me (and other users) some times... @martyhr could you solve it changing to 32 bits? and @klaus.krpano , is there any place where could we know on with device this issue will ocur? and also is there any effective diference between 32 and 64 versions?
Is happening in the 20 version. We are makeing a videoconference integrated tour so that is a big problem for us...

Thanks so much!

Hi, try these things:
- updating the GPU drivers (manually)
- reducing the memory.maxmem setting
- check if you are using large single-res panos/videos or hotspot images in your tour

Have this black screen stuff on some Oppo phone as well. But can't trace | provide the console warning yet.

Any ideas please?

The viewer also encountered the same problem. Will the next version fix it?
