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).</pre>
