Problems/Framgents with post processing bloom/lens flares

Hi,

I have the following problem. In the scenes where there is a lot of sunlight, my lit image with bloom or lens flares look like this:

All values ​​for bloom and lens flares are default, I can fix this problem by setting r.PostProcessAAQuality lower 3 but I need a good antialiasing quality so this is not an option.

I felt I had tried everything out but I couldn’t find the solution.

If you have any ideas it would be great

Thank You
