Significant performance loss after reloading compute setting when auto contrast is on

[NoeTopeza]

Changing/reloading compute settings or camera decrease significantly the applications performances (observable on the speed at which the input queue empties itself).
Functions MainWindow::reload_ini(const std::string& filename) and MainWindow::change_camera need to be examined.

Observation: the quantity of memory taken by the app appear to increase by a fixed/proportional amount when changing/reloading.

[NoeTopeza]

Changing batchsize (reducing it) will increase the amount of memory the app takes.
Increasing it back doesn't shrink the memory used.
After further research, this bug isn't linked to the current issue and is much older (pre 12.10 !)

Also triggers when saving advanced settings

[NoeTopeza]

it's auto contrast
Activating it (even by deactivating it immediately afterwards) causes a loss of performance the next time the compute settings are reloaded, resolvable by relaunching the application after deactivating it.

It might have been fixed since then with an other issue, if not, I cannot see a major performance loss while playing with auto contrast on/off, nor saving advanced settings. In the picture linked, I cannot say there is any performance loss, nor memory leaks with the contrast, (In the picture, 1 is auto contrast on, 2 is auto contrast off) I only noticed that turning auto contrast off doesn't give back the memory, i don't have an explanation yet.
