Yousef, Canonical should and does notify people of known problems in the release notes [1]. We only failed/forgot to mention this one and its workaround in the release notes. Although scrolling up, it appears nobody figured out what the workaround was until after 18.04 was released. And even then only one person was experiencing the bug at the time. It took more time to get more bug reports and a clearer idea that it was specific to early-generation Intel GPUs. At the moment I'm having authentication problems and am unable to update the release notes...
As for a fix, it looks like upstream have found the problem just last night [2]. So hopefully a proper fix will be available to try soon.
