Hi friends,

I have multiple QwtPlots'(QwtSpectrograms) in a QTabWidget, each plot is displayed in a tab separately.

I am observing one weird behaviour while switching between these Tabs.

It is taking nearly 2 to 15 seconds to switch.
Depending on the data rendered in each tab(Plot). Some tabs might have less data, some tabs might have more data.

The application becomes unresponsive while switching between tabs

Please let me know about how to fix this issue.
