UI break when using chart description option in superset5.0

[sunilreddy0720]

Hi,

Need a bit of help here when i upgraded to superset5.0.

For all my charts, at my first load the dashboard and charts looks perfect. when i click on show chart description, the chart description appears on top of my chart which is fine, but when i click on hide chart description its affecting my actual chart size which is not aligned correctly like first render.

first dashboard load:

Show chart description:

Hide chart description:

This happens to all chart types in superset5.0

This is a confirmed bug in Superset 5.0+ caused by a timing issue with how the chart description height is measured. The root cause is that useEffect is used to measure the description container's height, but it runs after the browser has already painted — so when you hide the description, the chart doesn't recalculate its dimensions correctly [1].

PR #38307 addresses this by replacing useEffect with useLayoutEffect, which measures synchronously before the browser paints, ensuring the chart gets the correct height on every toggle [2]. You may want to check whether your build includes that fix, or cherry-pick it if it hasn't landed in your version yet.

As a workaround until you can apply the fix, avoiding the show/hide toggle (or refreshing the dashboard after hiding the description) should restore proper sizing.

To reply, just mention @dosu.
