Hello,
Lately EasyEda PCB designer is sooo slow, its just not workable! Moving or selecting items take over 30-60sec!
Giving the chrome error, page is unresponsive wait or close...
I tried swapping from Chrome to Firefox even to the App designer same issue, disable all un-needed features withing system BUT no change!
Whats going on?
6.4.31 is totally useless!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I no longer and do any work for all the above reasons!!!!!
Looks like @deskpro256 has the same problem (https://easyeda.com/forum/topic/4-layer-PCB-editor-lag-69999ef9802940cb816e469086516447).
And ihe is right about the plane layer, I have one in my project.
I tried to switch it from plane to signal layer and it's back to normal.

Any reaction from the designers?!
fixing this bug would be welcomed!
Aren't there any pre release tests?
A 4 layer board is anything but fancy these days
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Same for me, just updated to 6.4.31 today and it's impossible to work. It hangs at almost every time i try to draw a trace or when in move a component.
Tried on macOS Desktop App, Windows Desktop App, Firefox and Edge, it's the same behavior for all of them.
