I can confirm that using java 8 (openjdk) on 15.10 fixes rendering problems in skype. However one minor corruption occurs in IntelliJ IDEA itself when running on java 8 (openjdk) (see screen-shot).
After upgrade to 16.04 as of 8 Dec 2015, none of java versions cause any corruption in skype, however now both java versions - 7 and 8 (openjdk) - exhibit the corruption in IntelliJ IDEA as in the attached screen- shot. ** Attachment added: "IntelliJ IDEA corruption" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1507484/+attachment/4531987/+files/intellij-idea-corruption.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1507484 Title: Window Graphics Corrupted for Skype To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1507484/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
