Brave browser save unconsented screenshots of page

[Purku]

Description of the issue:
I notice that Brave Browser save screenshot of page on folder /data/data/com.brave.browser/app_textures/ even the Private Tabs.

Maybe this is Chromium feature to save state for preview of tab or not? But include the private tabs where thumbnail and screenshot is disabled? Unless enbled on flags brave://flags/#incognito-screenshot

My guess is that it is used for preview for Recent apps but with my unupdated Chrome browser it only save “encrypted? (PKM?)” format. While with Brave Browser it save an viewable images.

It concern me as Brave browser’s tag is:

The best privacy online
Browse privately. Search privately. And ditch Big Tech.

How can this issue be reproduced?

1. Open Brave Browser
2. Open Recent apps to preview Recent apps or press Home to minimize
