https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D198574 Kurt Jaeger <pi@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pi@FreeBSD.org Assignee|vbox@FreeBSD.org |pi@FreeBSD.org --- Comment #1 from Kurt Jaeger <pi@FreeBSD.org> --- Comment from Ralf Nolden (kde), so: testbuild@work I have checked that with Virtualbox and witout the patch I get the messages: Qt WARNING: libpng warning: iCCP: known incorrect sRGB profile due to wrong png files, which the patch fixes. I applied the patch from the PR and rebuild virtualbox, then retried. The errors are away now. More info on the underlying issue is found here: https://forum.qt.io/topic/58638/solved-libpng-warning-iccp-known-incorrect-= srgb-profile-drive-me-nuts http://www.libpng.org/pub/png/libpng-manual.txt Error detection in some chunks has improved; in particular the iCCP chunk reader now does pretty complete validation of the basic format. Some bad profiles that were previously accepted are now rejected, in particular the very old broken Microsoft/HP sRGB profile. The PNG spec requirement that only grayscale profiles may appear in images with color type 0 or 4 and that even if the image only contains gray pixels, only RGB profiles may appear in images with color type 2, 3, or 6, is now enforced. The sRGB chunk is allowed to appear in images with any color type. --=20 You are receiving this mail because: You are the assignee for the bug.=
