Silhouette UNDO bug issue

Hey, While we do paint in Silhouette 2020, Some kind of error message pops up showing “Silhouette has detected that the undo system has gotten out of sync, Reset the undo state?”

After that if we try to do Undo, It wont work and also If we check the Undo option in edit (menu bar), we can notice there like undo is hidden and it shows Can’t undo. I always notice that this kind of bugs comes, while painting using wacom pen. If we do save as also we wont be able to make the Undo option enabled. Only when we close the silhouette and open again - its coming back to normal
While the error occurs, we can use the other tools, Only the Undo state doesn’t work.

Yes we have seen this before but can’t reproduce it. Can you detect any behavior patters that trigger it? Maybe certain modifier keys being held or commands being triggered while painting?

When ever we use paint node with Wacom pen, suddenly the bug pops up without any warning or lag in software. When we restart the software the undo state becomes active from hidden.

On my machines, I can’t reproduce this, so a set of steps that can reliably reproduce the issue would be helpful.

That’s understandable, But even I am not able to predict when this issue is gonna come. So I am helpless now, Sorry!

I have just had the same error. It was created after I trimmed footage and dragged that trimmed sequence into the “Trees” view to create a new session. I started a fresh project as well as restarting and reopening the project but in both cases I could not recreate the error.

I’m currently finding that Undo isn’t working in Silhouette Paint. I’m doing some cloning in 32bit Float mode.

Welcome @Nathan
Did you receive an error message?
Does Undo start working if you exit Silhouette and then restart it?

Hi - no error message. However I’ve been experimenting and discovered the following:
Same issue is present whether using Premiere and After Effects.
Have restarted Silhouette and the host software.
Same issue is present in Float 16 and 8bit mode.
Trying to Undo disables the selected tool (eg Clone or Paint), it remains disabled until I switch tool.
The preview in the host software (eg After Effects) does not update after exiting Silhouette Paint.
Moving the project onto other external / internal drives makes no difference.

I will try restarting my computer next, I’m just waiting for an upload to finish.

Thanks!

Computer restarted, reset plugin cache - problem remains.

Are you running the most recent version of Silhouette which is 2020.5.6?

Undo is working for me. If I paint multiple strokes, I can undo each one of them. Is this not working for you?

I do see that if you create a new project, paint and then Undo all of the steps, you have to switch brushes before you can paint again. That is a bug.
