@kurayami07734 Thanks for the great work. Is it possible to:

1. change the pixel size in accordance to the tool size that the user is using?
2. considering that its a drastic change, can you add an item in the settings that allow the user to toggle this on/off? This is good for privacy, but it now looks like an extra opaque layer. This may cause backlash from users.

I did not find where exactly the pixel size is being set

considering that its a drastic change, can you add an item in the settings that allow the user to toggle this on/off? This is good for privacy, but it now looks like an extra opaque layer. This may cause backlash from users.

I tried to add a setting for this in my latest commit. I followed the example of other settings already present. I am some how getting a segfault now

QLayout: Attempting to add QLayout "" to SidePanelWidget "", which already has a layout

Edit

I've narrowed it down to QAbstractButton::setChecked(bool)
I am probably not using the connect function properly

Hey guys, you probably missed this PR

@kurayami07734 I'm reviewing your PR now. Sorry about the wait.

Is it not the same issue as #2439, #3323, #3242 etc ?

The current blur tool can be set at max size by scrolling and I think the effect is very satisfying. I'd rather have it than these little dots (no offense). It may not be clear enough that the scroll can be used for size though.

I've randomized the pixel using std::random_shuffle, so it looks like white noise a bit.

Also, can I run flameshot from wsl?

Ah my bad it will be a separate toggle/option. Cool.
