Hi my specs are: Experimental 2D LWRP Lights (uses custom Renderer2D that uses the resultant shader) Unity 19.2.0b10 (this is beta) LWRP 6.9.1 Shader Graph 6.9.1 Shader Graph tends to freeze (randomly?), for ex when: 1) create node / custom function 2) add some inputs 3) add some outputs 4) set type to string 5) write function body ^ sometimes freezes as soon as the cog icon is clicked to modify the custom function node, sometimes freezes as input is added, sometimes when one attempts to add function body code (clicking the input field to write function body becomes irresponsive), while the shader graph can sometimes be closed and reopened which un-freezes its functionality, rarely the whole Unity engine becomes irresponsive, requiring process kill (windows). Its extremely annoying as it happens multiple times per minute (should be trivial to detect), changing something minute might freeze the SG window, requires reopening. My hope is that Someone has experienced this and can recommend a resolution (downgrade from unity beta/try alpha/try different package version(happened in last 2 SG versions for sure), or anything else. I post this in hopes that its a known issue and someone can easily steer me in the right direction.
