#2910: Heatmap | Memory issue when heatmap contains molecule columns #2910

Closed katerina-stepanova closed 4 days ago

katerina-stepanova commented 3 weeks ago

v1.18, 1.19

Steps to reproduce:

  1. Open a table with molecules, e.g. SPGI
  2. Open filters (not sure if necessary, but it looks to worsen the issue)
  3. Add a heatmap
  4. Configure heatmap to contain Structure and R groups columns
  5. Adjust vertical zoom slider on heatmap, move it up and down OR change heatmap viewer size so that it is re-rendered
  6. Monitor memory used by the browser page

Expected results: heatmap is re-rendered without issues or warnings. There should be no memory leaks and out of memory crashes. Actual results: Page freezes for a while and multiple warnings appear in the console: Molecule not rendered due to width or height less than 1 Page starts to take more and more memory on re-rendering the heatmap (when vertical zoom is adjusted or viewer size is changed). For some larger datasets page eventually crashes with 'out of memory' error.
