10 years ago Occasionally I find that after leaving the desktop alone for a while, switching workspace will reset the issue for a while. Eventually it comes back. The applications I am using are things like Eclipse, Oracle SQLDeveloper, Thunderbird, Chrome, Firefox, VMWare Horizon View Client, LibreOffice, Pidgin. I develop various Java-ish web applications on the machine using GWT/GXT, Hibernate, Grails etc. It appears to be unrelated to what application I am using - it has happened with no applications running and after a reboot with no applications auto loading apart from the standard set plus nvidia-settings. I do run Pidgin at startup but that did not affect the issue. While there may be application interactions, I don't think its that, as the issue simply does not arise unless I use the rendered switcher.
Using Ctrl+Alt+ Down arrow to use the individual window switcher resets the condition and the display is corrected - so whatever its doing is resetting the render mode correctly. Its not necessary to reboot or restart the desktop manager.
While this is no show stopper (I use the switcher applet instead), it would be good to get it fixed as its a bad look for an otherwise brilliant desktop.

Linux Mint 17 'Qiana' - Cinnamon 64 bit Cinnamon version 2.2.13 Intel Core 15 650 @ 3.2 GHz x 2 Memory 8 GB 120GB Samsung SSD NVIDIA G73 (GeForce 7600 GS) NVidia video driver version 304.117 and 304.121
When pressing Ctrl+Alt+up arrow to display the workspace switcher panel, characters rendered by Cinnamon are replaced with partial rendering only - that is black squares where the characters would be, or in some cases letter shaped shadows, and the vanilla mint menu icon is displayed. Attached screenshot shows that time desklet is also affected. Applications are not affected, so it does not appear to be a general driver rendering issue.
Using the Ctrl+Alt+L & R arrow keys to switch workspaces or the workspace switcher taskbar applet does not affect rendering at all, so the issue appears to be related to the rendering of the workspace switching panel itself. Possibly switches to a specific rendering mode and does not switch back?
This happened when using the recommended driver (304.117) and the newer driver from NVidia (304.121), so I think it may be a general driver interaction issue. I don't know whether it happens in the Nouveau driver - I never use that.
Problem is reproducible approximately 70% of the time.
