I have attached a few images of a reproducable bug whereby entering a large text input to the FFFFFF hex value area of a brush colour widget causes my graphics card to crash / reboot (goes into basic colour scheme mode) and all other graphics problems happen.
Steps:
Create a “Set Brush Color” node.
Copy the “Set Brush Color” node
Open the “In Brush Color” color picker
Go to “Hex” input field
Right Click > Paste
This (on my end) stalled my graphics card and created the following artefacts.
I’ve attempted reproducing this under the conditions you seem to be working under, but haven’t been able to repro. Can you send along your dxdiag? Also I’d like to know exactly what you have in your clipboard when you paste. Is it “FFFFFF00”?
Also if you follow the steps between 2-5 i do the following:
Copy the “Set Brush Color” node
Open the “In Brush Color” color picker
Go to “Hex” input field
RightClick > Paste
Which results in pasting the underlying code for the “set brush color” node into the colour string value, it was a mistake, but it messed my graphics up.
