Hi! I have just compiled one testing plugin with the latest commit from branch juce8. Unfortunately, the buffered image issue (which was solved once, see Clipping and custom fonts - #22 by matt) appears again.
Here is a screenshot of the testing plugin GitHub - ZL-Audio/ZLTest at juce8 :
The first row is with setBufferedToImage=True and the second row is without the buffered images. It ALSO refuses to paint those horizontal lines (second column, second row) (which is similar to the second point of @fuo )
I am using VMWare Fusion on macOS (with 2.6 GHz 6-Core Intel Core i7 & Radeon Pro 560X) to host Windows 10 22H2 with full resolution for Retina display (not sure about the scaling since VMWare handles this, but not 100%).
