Steps causing the bug to occur
- Create a composition that has more than 3 Image Feedback nodes
- Play push video data into all three
- Either composition crashes on ATI based x4000 GPU systems, or adding another Image Feedback will crash system
-
-
Have you found a workaround?
Use less Image Feedback Nodes, max 2.
Other notes
- How severely does this bug affect you? It prevents me from completing a specific task with Vuo.
I believe this may be related to the currently known x4000 GPU Driver bug that occurs when rendering multiple textures. I am letting Team Vuo know about this behaviour as I knew about the x4000 bug with nodes such as Scene Make Image
but not with Image Feedback
.
Current and only work-around for me is to use a Nvidia GPU.
Looks like the same underlying problem as bug report X4000 graphics driver crashes.
For that other bug report, the problem involves Render Scene to Image
. Image feedback, for this bug report, uses the same underlying mechanism (OpenGL FBOs).
Other nodes that may be be affected:
Render Layers to Image
Render Scene to Stereo Images
Warp Image with Projection Mesh
- image filters
- 3D object filters
I’ll make a note to remind us to test image feedback when addressing that other bug report.
Thanks @jstrecker, I really did get an appreciation of how serious this bug is when building a live video engine for our Cave Show over the weekend. Lots of Render Layers to Image
were used so I could fade multiple elements in with a MIDI slider. I’m just glad I had a Nvidia GPU handy! My first large show on Vuo! The beginning of many! ;-D
