[Bug 1780846] Re: After update 2018-07-08 menus and buttons are behaving badly

[Daniel Novotny]

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)

Title:
  After update 2018-07-08 menus and buttons are behaving badly

Status in mesa package in Ubuntu:
  Confirmed

Bug description:
  After an update to

     Description:	Ubuntu 16.04.4 LTS
     Release:	16.04

  Menus and buttons are behaving badly. This is a general issue, affecting most programs.
  Text in buttons is not always being displayed.
  When you mouse over an entry in a menu list the previous entry disappears
     e.g. the logout menu (power button icon at top right of panel)
  Menu items are getting red backgrounds where they were not before.
