            Bug ID: 111889
           Summary: Severe glitches in cinnamon/gnome3 affecting small
                    rectangular areas (menus, dialogs)
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: not set
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: sdiconov@mail.ru

Unreadable file copy dialog (cinnamon filemanager)

I witness a gradually developing regression that results in increasingly nasty
graphical glitches in the cinnamon and gnome3 desktop environments. It has
reached the point when it becomes impossible to see, what GUI button or menu
item you are clicking, which makes the whole desktop unusable.

The bug affects relatively small rectangular areas containing individual GUI
elements. See attached screenshots. 
* Dialogs that are close to a square in shape are less likely to be garbled,
Wider dialogs look worse.
* The bug disappears immediately if I run a different desktop compositor using
commands like "compiz --replace".

Affected DE-s: 
- Cinnamon  (strong)
- Gnome3 (less)

Not affected DEs|WMs:
- mate
- muffin (cinnamon wm run independently of its DE)
- compiz

KDE not tested by me.

My hardware and kernel:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Turks
XT [Radeon HD 6670/7670]
Linux kernel 4.19.72, radeon.ko driver 

The regression started with small systray icons, than it spread to hint and
notification boxes. Since about a week ago (my latest update) it affects menus
and dialog boxes as well. The same dialogs that become ureadable in cinnamon
may look normal in gnome3 (without normal wm titlebar).

What component (mesa, kernel, etc.) did you change which caused the regression?

It is difficult to tell exactly. The regression developed during a series of
whole-system upgrades executed by the command "apt-get dist-upgrade". It
included minor kernel upgrades in the range of 4.19.xx.

I primarily suspected cinnamon built-in compositor before. Now I would probably
blame the code coming in the packeage "xorg-drv-radeon". I lack the knowledge
needed to say if mesa or gtk3 are responsible too.

Current versions are:
xorg-drv-radeon-19.0.1-alt1.x86_64

libGLX-mesa-19.1.7-alt1.x86_64
libEGL-mesa-19.1.7-alt1.x86_64

libclutter-gtk3-1.8.4-alt1.x86_64
libgtk+3-3.24.11-alt1.x86_64
cinnamon-4.2.4-alt2.x86_64

if that helps.
