           Summary: [KMS] rv280 and  tiling corrupt some apps
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: randrik at mail.ru
         QAContact: xorg-team at lists.x.org


I have radeon rv280:

01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 SE]
(rev 01) (prog-if 00 [VGA controller])
        Subsystem: Hightech Information System Ltd. Excalibur 9200SE VIVO 128M
        Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16
        Memory at c8000000 (32-bit, prefetchable) [size=128M]
        I/O ports at b800 [size=256]
        Memory at d7ef0000 (32-bit, non-prefetchable) [size=64K]
        Expansion ROM at d7ec0000 [disabled] [size=128K]
        Capabilities: [58] AGP version 2.0
        Capabilities: [50] Power Management version 2
        Kernel driver in use: radeon
        Kernel modules: radeon, radeonfb

(note: i don't have radeonfb loaded, it blacklisted)

with software versions listed below i have serious corruption in Eterm, xcalc,
xxkb. Disabling DFS fixes xxkb, but other apps remain broken. Playing with
ExaNoUploadToScreen has no effect (should it have any in KMS mode on radeons
?).

Enabling composite manager (built-in into e16 1.0.0 WM) fixes this bug. GTK2
apps are ok even without compositor.


software:
