stonegrass example causes GPU timeout on its default resolution (and higher) #68

Open 20kdc opened 1 year ago

The stonegrass example, if left at its default resolution of 1024x1024, causes GPU timeouts (at least with amdgpu.gpu_recovery=1).

The GPU recovery is followed by the complete failure of texturelab's rendered UI elements, as shown here:

From looking at the rendering timings, my theory is that this is due to an intensive use of the Tile Sampler node.

It is worth noting that the following two steps avoid the crash:

  1. Extremely quickly after loading the file, change the resolution to 512x512 from its default of 1024x1024. If done in time (feature request: update mode of 'None' that persists across loaded files), the crash will be averted.
  2. After performing 1, one may reduce the row and column counts to 30x30 - it will then be safe to increase resolution to 1024x1024. It is not safe to increase resolution to 2048x2048.
