Created attachment 139487 [details]
As the description says, vertical lines with dasharray 1,1 do not render (probably Skia related).
In the attached testcase you should see a grid of dotted lines but Chrome just renders the horizontal ones.
Original bug: crbug.com/35796
It does seem Skia related, it works fine in QtWebKit and Safari trunk.
I am unable to reproduce this bug in Safari 15.5 on macOS 12.4 and also on Safari TP 148. It matches with all other browsers (Chrome Canary 105 and Firefox Nightly 104). Even the corresponding Chrome bug was marked as WONTFIX after someone tested in 2014 and concluded that now it is working as intended.
If it is still issues on other Webkit builds then I think it can be kept open else I think we can close it (if there is any WPT or test case coverage available to capture this). Thanks!
Resolving as INVALID, as this only ever affected Chrome.
