Random nodes will "jitter" on preview2d in some occasions
Material Maker version: 1.4a
OS/device including version: Windows 11 Lenovo laptop with a NVIDIA GeForce RTX 2060
Issue description: On some rare occasions, trying to preview a random node output on preview2d will cause it to "jitter" for a few seconds, appearing to rapidly change seeds, before stabilizing in a single state When the bug occurs in a material, the jitter will occur even on nodes that are not connected to the shader.
Steps to reproduce: Bug can be reproduced with the following node chain:
{"connections":[{"from":"transform2_4","from_node":"node_transform2_4","from_port":0,"to":"blend2_2","to_node":"node_blend2_2","to_port":3},{"from":"voronoi_triangle","from_node":"node_voronoi_triangle","from_port":1,"to":"warp","to_node":"node_warp","to_port":1},{"from":"transform2_3","from_node":"node_transform2_3","from_port":0,"to":"blend2_2","to_node":"node_blend2_2","to_port":1},{"from":"warp","from_node":"node_warp","from_port":0,"to":"transform2_3","to_node":"node_transform2_3","to_port":0},{"from":"warp","from_node":"node_warp","from_port":0,"to":"transform2_4","to_node":"node_transform2_4","to_port":0},{"from":"warp","from_node":"node_warp","from_port":0,"to":"blend2_2","to_node":"node_blend2_2","to_port":0}],"nodes":[{"name":"voronoi_triangle","node_position":{"x":-532.780029296875,"y":-187.380004882813},"parameters":{"randomness":0.85,"scale_x":3,"scale_y":1,"stretch_x":1,"stretch_y":1},"seed_int":1927375744,"type":"voronoi_triangle"},{"generic_size":1,"name":"transform2_3","node_position":{"x":27.2200317382813,"y":-87.379997253418},"parameters":{"mode":0,"rotate":0,"scale_x":1,"scale_y":1,"translate_x":0,"translate_y":-0.15},"seed_int":0,"type":"transform2"},{"generic_size":1,"name":"transform2_4","node_position":{"x":27.2200317382813,"y":172.619995117188},"parameters":{"mode":0,"rotate":0,"scale_x":1,"scale_y":1,"translate_x":0,"translate_y":0.2},"seed_int":0,"type":"transform2"},{"name":"warp","node_position":{"x":-252.779998779297,"y":-187.380004882813},"parameters":{"amount":0.065,"eps":0.2,"mode":0},"seed_int":0,"type":"warp"},{"generic_size":2,"name":"blend2_2","node_position":{"x":289.120025634766,"y":-182.480010986328},"parameters":{"amount1":1,"amount2":1,"blend_type1":12,"blend_type2":12},"seed_int":0,"type":"blend2"}]}
Previewing the "blend" node, or any node that takes it as an input will cause the seed on preview to jitter for a few seconds, the issue also occurs when replacing the preview of the glitched node chain by any other node, even if unconnected. Jittering also sometimes happens when a node in the glitched chain is updated.
Example:
I'm also having this issue, in my case it makes using Advanced Tiler nodes difficult. It's hard to see the changes I'm making through the jittering.
Also facing this issue on my machine. I wonder if it's graphics driver related.
I am running on Windows 10, and an RTX 2060.
