cursor is not erased in old position in evolution

[StefanS42376868]

Binary package hint: evolution

While editing a new message in "evolution" the cursor is sometimes not erased in the old position when I move it e.g. with the cursor keys. This results in many cursors, only one of them is the real one.
This bug occurs ALWAYS after resizing or re-activating the message window. When I start entering text into a new window, it does not occur.
This bug does NOT occur in other applications like e.g. gedit, so it seems to be an EVOLUTION bug.

The screen shot can be reproduced as follows:
1. Open new email message ("Neu")
2. Set cursor to message section and type "1234567890"
3. Activate another window and reactivate the message window
4. hit 10 times the cursor-left key

I forgot the version numbers:
Ubuntu 8.04
Kernel 2.6.24-18-generic
Evolution 2.22.2

thank you for your bug report what video and driver do you use? do you use the desktop effects option?

[StefanS42376868 (stefans42376868)]

I have the nvidia-glx driver and desktop effects "normal".

I have just found out that the bug does not occur any more when I switch off desktop effects completely!

My GPU is a "GeForce4 MX". According to NVidia, I should install the
legacy driver instad, but this seems to be impossible:
The "nvidia-glx" driver is automatically installed via System → Administration → Restricted Devices Manager.
I tried to choose "nvidia-glx-legacy" in System → Administration → Synaptic-Paketverwaltung (sorry: German), but the driver is not accepted there.

[StefanS42376868 (stefans42376868)]

I checked again and installed the correct driver:
nvidia-glx 1:96.43.05+2.6.24.13-19.42
The problem still occurs as soon as I switch desktop effects to "normal".

So it is a bug in the NVIDIA driver?

[Sebastien Bacher (seb128)]

could you try if you get the issue using the opensource nv driver?

[StefanS42376868 (stefans42376868)]

surely I would, but where do I find it? I googled without success...

[Sebastien Bacher (seb128)]

that's the standard opensource driver you have on ubuntu before installing the nvidia closed source one, just change your xorg configuration or uninstall the nvidia one

[StefanS42376868 (stefans42376868)]

With this driver I cannot activate the desktop effects, so I cannot check.

[Sebastien Bacher (seb128)]

either a compiz or driver bug, reassigning to compiz

Looks like this is a problem with using loose binding with the nvidia driver. As of right now we have to choose between these random redraw problems or incredibly poor performance but apparently there is some work going on upstream to make a sort of hybrid between loose binding and strict binding that should fix this problem without sacrificing performance.
