app hangs when looking at details of a JSONB field

[ccurvey]

1. Create table containing a JSONB field
2. Populate the JSONB field
3. In the query tool, run "select * from mytable"
4. double-click on a cell for the JSONB column
5. try scrolling to the right to see more of the data. App will hang

I'm not sure if it's related to large values in the JSONB field or not.

I'm running PgManage 1.1 on Ubuntu 24.04 (fully patched) using MATE for my desktop.

Hello. I have tried to reproduce this issue and can confirm that the app may be slow with large amounts of data in the cells. In my case app did not hanged completely but was very slow with data from this file : https://raw.githubusercontent.com/json-iterator/test-data/refs/heads/master/large-file.json
I don't think there is a quick solution to that though. I'll leave this ticket open, hopefully we can figure something out later.
Thanks!

A possible solution for this would be to implement cell-level lazy-loading so we don't waste network traffic and memory until the data is requested by the user.
