Comment 110 for bug 291055

Hi,

I just want to report much much stronger corruption all over the place with my HD4770:

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon HD 4770 [RV740] [1002:94b3]
        Subsystem: ATI Technologies Inc Device [1002:0d00]

As I'm currently using Kubuntu 9.10 Karmic with mainline Kernel 2.6.32 I wanted to finally give radeon KMS a shot but to no avail as it just displays totally garbage on my big Dell 30" (2560x1600 native). So I'm stuck with UMS but at least it "works".

I can see the first corruption when I log in using KDM when animations are displays after providing the credentials. Then when starting to work the desktop seem fine at first. The next things that are corrupted is the KDE4 main menu and when browsing with dolphin any graphic sooner or later become corrupted. This goes on as I continue to do things.

In contrast to that glxgears/-heads don't show any corruption. So I tried to enable desktop effects with the result that all window decorations disappear immediately and windows cannot be raised/lowered/moved/resized, shortcuts like ALT+F4 doesn't work any longer but the applications itself continue to work.

I'll attach some screens for further details.
