Text corruption in various Gnome apps since Xenial upgrade

[Marlin Forbes]

Description: Ubuntu 16.04 LTS
Release: 16.04

Since the Ubuntu Xenial upgrade, I've had various instances of text corruption. I use a gnome-shell session. I (think) see this only if the laptop has suspended and restored.

I'm using the intel graphics driver from ppa:oibaf/graphics-drivers (in a failed attempt to try and upgrade myself out of the issue), but it was happening before changing to a custom PPA.

This affects such a wide array of parts of the desktop that I suspect it's likely to be a basic X11 driver or GTK-level bug.

Screenshots attached.

that looks similar to https://bugs.freedesktop.org/show_bug.cgi?id=88584

Thanks, let me try that solution first and see if I get it again. It's difficult to reproduce reliably.

I've been running that environment variable hack for a day now, and I'm still experiencing similar issues. Right now, all the text in the gnome-shell is gone. Window title bars, all the text in the gnome shell dash. Added attachment. I can't see the letters I type or the results that come up. It looks like I've run out of text resources or something at a very basic level.

Extra characters at the end of /etc/fstab were causing grub2 update to make boot say there was no root. All I had to do was remove a lot of invisible characters added to /etc/fstab.

I could not get my x environment to load, just kept cycling back to graphic login screen as if I had typed a bad password but there was no message to that effect. I can now use xfce, but not unity.

At some point I got into new grub2 code which no longer works with the search --no-floppy line in /boot/grub.cfg. That's not extra characters, sorry, but it's really obvious that menuentries in grub.cfg no longer boot and then x won't boot and with extra characters in /etc/fstab that's a second way grub2 menuentries won't boot, so how does this stuff get by untested?
