Bug #: 47765 Summary: Corrupt rendering to a window between 57 and 63 pixels high Classification: Unclassified Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: tvrtko.ursulin@onelan.co.uk
We are seeing render corruption when rendering a texture to a window between 57 and 63 pixels high. glViewport being set to window dimensions.
Texture vertices do not seem to matter. If I render to the full viewport, or to a subset of a viewport, always the whole viewport gets corrupt (so including the area outside texture vertices).
Texture size does not seem to matter.
Rendering is done with glDrawArray GL_TRIANGLE_FAN and the destination window is RGBA.
Environment:
00:01.0 VGA compatible controller: ATI Technologies Inc AMD Radeon HD 6310 GraphicsATI
Kernel 3.3.0 + 0001-drm-radeon-add-support-for-evergreen-ni-tiling-infor.patch
It does not happen without this patch - so it is probably tiling related.
xorg-drivers-ati, mesa and libdrm from yesterday's git. Last one is in fact a bit older, but I applied a single interesting patch (9b3ad51ae5fd9654df8ef75de845a519015150bb) by hand to make it up to date.

/usr/lib64/mesa/tri shows it if you resize the window right.

No, still the same corruption.

Unfortunately not, still the same behaviour.

This should fix your issue (patch against ddx xf86-video-ati)

Doesn't help on my rv790 - I am testing just this patch not the kernel one.
FWIW I only see this when swapbufferswait is off, looks like most/any mesa demo will show it.

Works lovely, thank you!
Interestingly we were on a similar track here trying to force something similar but in libdrm. But I am not surprised since I cannot say I picked up what component does what (kernel, libdrm, mesa, ddx) in the few weeks I've been in this code.
