[BUG] Graphical artifacts on the model catalog preview
General
- v0.8.3, 864bcc1 [P v1.3 Win64, 5767546]
Describe the bug When you open the model catalog, the preview on the right is full of graphical artifacts.
To Reproduce Steps to reproduce the behavior:
- Launch PFM
- Click on a selection (props, actor, etc) from the cog on the "Actor editor" tab to make the model catalog appear.
- The preview of the model catalog shows graphical artifacts.
Expected behavior The model catalog preview should be free of graphic artifacts or strange colors.
Screenshots
Hardware (please complete the following information):
- OS: Windows 11 24H2
- GPU: RTX 3070 Ti Laptop
- GPU Driver version: 572.16

Thanks for all the reports, I really appreciate it! I wasn't able to replicate this one on my side, so just a few questions to try and narrow it down:
- Does it only happen in the preview windows of the model explorer, or does it happen elsewhere as well?
- Does it happen every time, or only occasionally?
- Does it happen with every model, or just specific ones?
No problem, i hope to be of help 👍.
Does it only happen in the preview windows of the model explorer, or does it happen elsewhere as well?
Yes it happens elsewhere too, in fact i was going to open a separate issue for it but may as well put it here. Another place where it happens is when rendering a preview in the render tab but with a few caveats:
- Must be the first preview after starting PFM
- Pragma must be the selected renderer
- The size of the window and the objects in the scene seem to affect it somewhat changing how it shows up. A few examples:
- Default project, default window size, it shows up every time.
- Default project, window maximized, sometimes it shows some purple squares, sometimes it comes out right:
- pfm_demo_scene, default window size, it shows up everytime:
- pfm_demo_scene, maximized window, sometimes it shows something like superimposed part of the same map?, sometimes it comes out right:
Here is engine dump and log after for one of the tests if it is of any help:
engine_info_dump_2025-02-10_18-06-12.zip
Any preview after the first one or with CyclesX selected comes out right free of artifacts.
Also, I have found how to launch the VR mode through the VR Manager at the "Actor Editor" tab(i guess it's the same as the "Virtual Reality" option at the viewport?) and while in VR the artifacts appear too, sometimes is just one eye, other times it's both. It seems to be affected if i make a preview just before enabling the VR Manager.
Does it happen every time, or only occasionally?
For the model explorer it is every time.
Does it happen with every model, or just specific ones?
On the model explorer it happens even without a model selected, open the model explorer and the artifacts are already there.
Looking at those screenshots, I'm pretty sure it's a VRAM issue due to the huge resolution. Is that 4k? Just for testing, could you please try changing your desktop resolution to 1920x1080, then launch PFM and see if it still happens?
Yes it was 4K, it is a second screen, the other screen i have it's the one from the laptop, a 1080p panel. I unplugged the external 4K screen just to be left with the the laptop screen and rebooted, just in case. Still the same issue for both the model explorer and first render preview with Pragma.
Could you please check your VRAM usage in the task manager the next time it happens and tell me what it says?
Also, could you run debug_textures and debug_render_memory_budget in the console and post the output here?
Yeah, no problem. I have recorded a short video triggering the artifacts with the task manager on the side.

Also here is the output for both commands after triggering the artifacts in the model explorer:

I don't now if this narrows things, but I managed to, somewhat, make the artifacts dissapear by maximizing and restoring the window a few times just after starting PFM. It doesn't work 100% of the time though, but for the most part it seems to remove the artifacts in the model explorer.
@leronoa Can you try and do another preview render (with the Pragma renderer) with the latest preview release and check if the artifacts still appear? https://github.com/Silverlan/pragma/releases/tag/nightly
I've added some rendering fixes, but I'm not sure if they're related to your issues.
I tried the new nightly but unfortunately i am getting the same results.
Also a thing i noticed trying stuff around that i don't know if they might be related to this. When PFM is generating the model icons for the model browser you can see in the top left corner of the window a miniature of the current viewport. It seems to flash for each model icon that is generated.
With the latest nightly release, can you please try this:
- Launch PFM
- Run
pfm_debug_dump_render_image_stages 1in the console - Use the Pragma renderer to render a full image
- Upload the image files in
pragma/temp/render_image_stageshere
Also, can you check if the image output file also has those artifacts? You can find the file by clicking the gear-icon and then clicking "Open Output Folder":
(You might have to close PFM after the render, or the file might not be completely written yet.)
Yeah, no problem. The images generated by the pfm_debug_dump_render_image_stages 1 in the temp folder:
And the full render in the output folder:
It seems like it's reading from some type of buffer or cache. If i import a glb model and then render with pragma one of the textures of the model i just imported, but that i didn't use yet, would show up distorted all over the render like this:
