Can you set If you can't share the code, maybe try to make a minimal example showing the behavior. |

Thanks! I have now enabled the options you suggested, and will update this issue when I manage to capture this issue again (it's quite intermittent, which is also why I've had difficulty creating a reproducible example). |

Have managed to trigger it again. Images from formatted plotly.js for the top few frames in the stack trace: |

Turns out this was actually very easy to reproduce - it seems like any figure containing Scattergl traces and a variable subplot layout will cause this issue. In the app below, moving any sliders will cause the figure to crash. Using import dash
from dash.dependencies import Input, Output
import dash_core_components as dcc
import dash_html_components as html
from plotly import tools
import random
app = dash.Dash()
sx = dcc.Slider(id='sx', min=1, max=5, value=1)
sy = dcc.Slider(id='sy', min=1, max=5, value=1)
app.layout = html.Div(children=[
sx, sy,
dcc.Graph(
id='graph',
)
])
@app.callback(
Output('graph', 'figure'),
[Input('sx', 'value'),
Input('sy', 'value')]
)
def callback(nx, ny):
fig = tools.make_subplots(ny, nx)
for ix in range(nx):
for iy in range(ny):
fig.add_scattergl(x=[random.random() for i in range(20)],
y=[random.random() for i in range(20)],
mode='markers',
row=iy+1, col=ix+1)
return fig

For further info, the issue is still present when updating to: And for more interest, when the figure starts throwing errors and stops responding, you can sometimes coax the plot back into life by double clicking on a subplot and then clicking on a slider to redraw with the same layout - but it can end up looking pretty funky (see below)! It also generally seems to be more likely to work when reducing the number of subplots instead of increasing.

I've recently updated all my Dash/Plotly depenendices to their latest versions:
I have a Dash app where the number and layout of subplots in one of my figures (consisting of lots of Scattergl traces) changes depending on user inputs. When the number/layout of subplots changes, sometimes I get the following errors in the Chrome console:
After this, the subplots seem to be drawn incorrectly (missing elements, incorrect sizes). If I trigger another redraw after this happens the figure is eventually drawn correctly. Unfortunately I can't share the app code but will see if I can reproduce it.
I was previously on the following, and had never seen this issue before (although despite this problem, in general drawing performance with my Dash apps is a lot better now):
