It seems you are disabling dmabuf renderer, right? is it because of nvidia? does it happen with the dmabuf renderer too?

Disabling the DMABUF renderer it looks like this. Without disabling it, it looks like this but with flickering as well. I don’t know if it is because of Nvidia but previous versions of WebKitGTK (both stable release and previous JHBuild builds) work fine. It’s just this JHBuild build that is like this, so something must’ve changed between the last time I did JHBuild build and this time.

Do you remember when was the last time you built WebKit from main with jhbuild? The flickering is because of nvidia, yes.

Last JHBuild was about a week ago, certainly under 2 weeks. Since then I have been unable to do JHBuild again because of build failures. I check again every couple of days until today, after a git pull I can build without failures again.

Ok, so it's a recent regression then
