Makes browser to crash.

[KesavarajaRK]

Issue: Browser crashes with frequent undo.
Reproduce Steps:

1. Add more than 300 objects into the canvas.
2. Execute undo every second.
3. Browser asks to wait or stop the process. Continue with wait.
4. Once page is back giving undo back-to-back ends with crashing the browser with blank page.

Same issue. Do you have a solution yet?

Hi, this library is a pretty basic implementation of history logic. 300 objects can be a problem, and it also depends on the object's details as well. To be able to support such logic, you might need to use some other storage and logic, e.g., max 100 history, and the rest will be deleted as FIFO.

Ok, thanks u so much. An unrelated problem with your library, please help.
When I add an image to Canvas, if I add it as url then when I output with toDataURL it gives the error "Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.", currently I am bypassing by converting a to base64, but when I work with about 300 objects then it started lagging, don't know if you have any solution?
