   ### Steps to Reproduce
   
   Use the candlestick-brush example and change one of the MA lines to type "scatter".
   (full transparency: i've also changed the opacity of the lines to improve visibility).
   
   Now flick the scroll wheel - until you see a "rendering problem" appear.
   
   
   For the video, i've also added a bar-chart - which makes reproduction slightly easier - but the bar-chart is not really necessary (the problem happens on either bar or scatter or both - combined with the candlestick chart.

   setting "large" to true on all line / scatter series does not make the problem go away.
   
   
   
   ### Current Behavior

   ### Expected Behavior
   
   Well - no rendering issues in any combination
   
   ### Environment
   
   ```markdown
   - OS: linux
   - Browser: chromium, firefox
   - Framework: Examples...
   ```

   I started using FreqUI recently, which, apparently is based on these charts. With my config (multiple plots, multiple indicators) the problem becomes very bad very quickly, i.e. as soon as I try to zoom or move the chart. To the point where it is totally unusable :(
