I'm very interested in using the Datoviz library in an upcoming project. However I am encountering a problem: the render window is showing purely white other than ImGUI windows. I loaded the datoviz library in a pipenv virtual enviornment, and reinstalled GLFW with pipenv install glfw, but the issue persists. The issue is persisting no matter what datoviz code I attempt to run. I have tried both the demo and various examples. There is no error message or information being provided. A screenshot is below; any help would be very greatly appreciated

Output of datoviz.demo()

I'd be curious to know whether the same issue arises if you build Datoviz from source and try using it from C directly by following steps 1 to 10 here (i.e. up to ./manage.sh demo scatter )

What is your hardware specification?

[quothbonney]

I'll try building it from source right now. This is a stupid question, but what exactly do you mean by hardware specification?

[rossant]

I mean what PC is this, a laptop, a desktop? Which hardware configuration and in particular which GPU?

Something else that could help: install vulkaninfo and post the output here (see https://linuxconfig.org/install-and-test-vulkan-on-linux)

[quothbonney]

Oh, my bad. I'm on a laptop, using an AMD Ryzen GPU. Currently trying to install the Vulkan SDK to build from source.

Got the same problem here, on an AMD Ryzen KUbuntu 23.10 laptop using vulkan-sdk :

shows a white window.

vkcube and vkgears works fine.

N.B.: ./manage demo gui works fine.

The attached log file is the result of running ./manage.sh test > test-log.txt 2>&1
This laptop (not a VM like the author of this issue) seems to have a very low cost GPU.

test-log.txt

[phstrauss]

Since I see two GPU on this laptop, the hardware integrated Ryzen one and the mesa llvmpipe, I've tried to force the use of the hardware one by changing line 16 of demo.c to :
DvzGpu* gpu = dvz_gpu(app, 0);
with no luck.
Oops the authors of this issue is not on a VM, my bad, and otherwise most of the tests displaying something simple to the screen works fine, it's only the scatter and mandelbrot demo showing a blank screen. The email I use for reading the notifications is now read, was at fault before.

[phstrauss]

Building mesa git from source and lunarg vulkan loader does not fix the issue for the scatter demo but I would need a switch to pass to the tests to select a GPU different than what is selected by dvz_gpu_best() cause now I've 4 GPUs, mesa ubuntu, mesa git, plus its llvmpipe each time.
