Created attachment 471750 [details] Before Attached is a screenshot of correct (before.png, WebKitGTK 2.44.2) and incorrect (after.png, WebKitGTK 2.45.3) rendering of the dotted line beneath the Blocks field and above the Attachments box on this Bugzilla. The newer version is pretty messed up. I assume (without evidence) this is most likely caused by cairo -> skia.

Can you still reproduce this, I cannot on WebKitGTK 2.45.6

Actually nevermind, the issue goes away if the window is resized, but can be broken initially.

I think it just depends on window size. Here it was fine initially, but broke as soon as I resized it.

This is also quite easy to reproduce in the Clang documentation pages, like https://clang.llvm.org/docs/LanguageExtensions.html#builtin-dump-struct I have managed to get the dotted lines to have some small artifacts with WPE, but somehow the issue is more noticeable in the GTK port. I will attach a screen capture.
