graphical issues with onboard

[Frederik Elwert]

I noticed a few severe graphical issues when using onboard in Ubuntu Oneiric.

First, when I choose to launch onboard on startup, the keyboard is only partially drawn and unusable.

Second, when I minimize onboard to a floating icon, the icon sometimes isn’t drawn correctly. It shows a blank rectangle and a ghost shadow at a different spot. It also isn’t clickable.

Since this might be related to my graphics hardware, here the information about my graphics card:

$ lspci | grep VGA
01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility Radeon HD 4200]

I’m using the radeon driver.

Attached, you find two screenshots showing the issues.

Thank you for you bug report. I too suspect that this is a graphics driver problem. In particular double buffering may be handled incorrectly for some reason. If you are feeling adventurous you could try disabling that in Onboard and live with flickering keys. Let me know if you do and I'll tell you how.

Some questions:
- What happens if you minimize and restore Onboard again?
- Are you seeing corruption anywhere else outside of Onboard?
- Have you tried another video driver (vesa, fglrx, possibly radeonhd)?

Reporting back:

- I also noticed this corruption with the notes overlay in evince.
- fglrx seems not to work with Unity at all.
- After a recent update, the problem disappeared.

So the problem seems to be solved for me, and probably it was related to the graphics driver instead of onboard itself.
