In the previous discussion everyone seems happy it’s been patched and not to worry (even though androids mostly don’t run anything like the latest android)

But in this write up they say the patch doesn’t work fully

App developers can already dynamically mark their windows as secure which should prevent any other app from reading the pixels it rendered. The compositor composites all windows, including secure windows and applies any effects like blur. No apps are supposed to be able to see this final composited image, but this attack uses a side channel they found that allows apps on the system to learn information about the pixels within the final composition.
