thanks for reporting, i tested it myself and on firefox it is very buggy, on windows it seems to handle it (maybe because the pc is better than a phone)

Umm After comparing Chromium and firefox (on Laptop with power mode on performance) both give nearly same performance when moving around on canvas. From my previous observations I think so my laptop was running on power saving mode

I think that, tools like path eraser and eraser are causing performance issue

Okay thanks. I just wanted to be sure I could reproduce this behavior. I will look at it and try to fix it

path eraser tool when delete an element whole visible area is canvas is rerendered. I am also not sure if it refresh objects what are not visible on screen

• the easer path pointer is also too slow
• Erasing path, misses paths , it could be due to slowness of pointer

thanks for testing, I will try to improve this a bit
