With both CB 8.xx and 10.05, my source editor pane corrupts text frequently during scrolling.
This results in an editor pane that looks like a corrupted image, with half lines of text being repeated, etc...
Clicking the mouse in the editor pane, to double click a word, or drag-select some text, or similar action, usually causes a refresh which removes the corruption.
Research on the internet did suggest that there was a similar problem with wxWidgets at some point, but I'm reasonably sure that this didn't start happening until after I installed a new graphics card (6870).
Updating to 10.05 did not resolve the issue, neither did reinstalling the graphics drivers (Catalyst 10.10b Hotfix). I'm using a custom syntax highlighting color scheme, and Consolas (at 16 or 18 pt, IIRC), in case it matters.
Have not tested the PCs RAM, going to do that tonight, but I can only reproduce the problem with CB.
Any suggestions appreciated...

Try Scite, it uses the same (almost) component for the editor.
Another thing you could try is CodeLite, I think it also uses wxScintilla for its editor.
-
Minimizing and resuming should fix it too.
But that's of course just a workaround, not a fix.
If I understand correctly, the issue starts after installing a new graphics card.
Seems to be an ATI/AMD problem: see here: http://www.overclock.net/ati/850691-official-amd-radeon-hd-6850-6870-a-130.html#post11460642 (http://www.overclock.net/ati/850691-official-amd-radeon-hd-6850-6870-a-130.html#post11460642) .
And after reading more of the thread, I think either the HD6870 or the drivers are not really stable.
If that's the case, we will (most likely) not be able to (easily) fix this.
-
Thanks, folks.
The 6870 is so new that Catalyst 10.11 doesn't even support it (I tired that, too :D).
I'll see what 10.12 brings, it does look like it's up to AMD to sort out.
At least I can probably skip testing my RAM...
Cheers!

Couldn't reproduce with Catalyst 10.12, problem appears sorted.

i recently update to ubuntu 11.04 and i also started having this 'scrolling-text-corruption' problem. i am using nvidia drivers 270.41.06
if somebody has found any solution to this, please share..
thanks
-
I too am seeing this problem. It started when I upgraded Ubuntu from 10.10 to 11.04. I have tried removing and then reinstalling codeblocks and the problem remains.
-
Talk to the ubuntu devs, this seems like a driver bug.
Do you use compositing?
I'm on gentoo and see no problems (nvidia 270.41.03)
-
I am running Ubuntu 11.04 in a vm on a macbook pro. When I was running codeblock in 10.10 I did not have this problem.
-
I just had the same problem with corrupted lines in the Code::Blocks editor after updating from Ubuntu 10.10 to Ubuntu 11.04 and changing from an ATI to an NVidia graphics card. I disabled Unity unintentionally and had to reset it with
unity --reset
from the command line. Although I do not know why, but this also made the editor problem disappear.

yes i am, i guess it is required by Docky and other compiz eye candies.
but then i have been using composting when i was at 10.10 and previously i never had any problem.
-
Composite was on before resetting unity and it is still enabled after the reset. Now the bug disappeared, i.e. in my case it did not influence the bug.
BTW: My NVidia driver version also is 270.41.06.
-
For me running in a vm on a MacBook Pro this does not seem to be a unity issue in Ubuntu 11.04. I have tried all display modes (ie. Ubuntu (unity), Ubuntu Classic, etc) and I am still seeing the issue. I had high hopes that Ubuntu Classic would resolve the issue but it did not.
-
Does Scite work correctly?
-
SciTE works. No scrolling problems in the editor. The display mode I am currently using in Ubuntu 11.04 is Ubuntu Classic.
-
i think this problem has vanished somehow may be because of some regular update.
So guys whoever of you are having this scrolling problem run system update btw i am using codeblocks 10.05 svn version http://apt.jenslody.de/ (http://apt.jenslody.de/)
with latest wx stuff

Update for Ubuntu 11.04 users... Editor scrolling problem is gone after doing a SW update from the update manager. Life is good (again) in CodeBlocks land
