David, if the workaround in Bug #1780664 works in our case (i.e. for this bug) we should change the affected component from "libdrm" to "mesa": I was searching for something related to graphics drivers to be responsible for this bug, thought it was libdrm, but it can be mesa, too. Have you tried the workaround? I did not for now, I have a lot of work to do till weekend: and in my case Firefox, Mplayer, Dosbox and Vim work fine, which are the programs I use most, so I am not very pressured to do the fix, maybe I will wait until the official fix is out.
I was also thinking that another thing that may fix this could be upgrading the kernel from GA to HWE according to this article: https://wiki.ubuntu.com/Kernel/LTSEnablementStack (the command when they say "DESKTOP") - but this can be dangerous and can break other things so I was not brave enough to do this upgrade: also the bug can maybe stay even when the kernel is updated this way which would be sad ** Package changed: libdrm (Ubuntu) => mesa (Ubuntu) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1780846 Title: After update 2018-07-08 menus and buttons are behaving badly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1780846/+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
