It's either a genuine wild write from a mesa batchbuffer or the finish-gpu-esque bug. Reassigning to Mesa because we have other SuperTuxCart bugs open and this may be related. Hi! I believe this was fixed by the following commit, which is already part of the Mesa 8.0.3 release: commit 93e94cbb48a679b7bf67594adb6f858526b37935 Author: Eric Anholt <eric@anholt.net> Date: Fri Feb 10 12:54:25 2012 -0800 intel: Fix rendering from textures after RenderTexture(). There's a serious trap for drivers: RenderTexture() does not indicate that the texture is currently bound to the draw buffer, despite FinishRenderTexture() signaling that the texture is just now being unbound from the draw buffer. We were acting as if RenderTexture() *was* the start of rendering and that we could make texturing incoherent with the current contents of the renderbuffer. This caused intel oglconform sRGB Mipmap.1D_textures to fail, because we got a call to TexImage() and thus RenderTexture() on a texture bound to a framebuffer that wasn't the draw buffer, so we skipped validating the new image into the texture object used for rendering. We can't (easily) make RenderTexture() indicate the start of drawing, because both our driver and gallium are using it as the moment to set up the renderbuffer wrapper used for things like MapRenderbuffer(). Instead, postpone the setup of the workaround render target miptree until update_renderbuffer time, so that we no longer need to skip validation of miptrees used as render targets. As a bonus, this should make GL_NV_texture_barrier possible. (This also fixes a regression in the gen4 small-mipmap rendering since 3b38b33c1648b07e75dc4d8340758171e109c598, which switched set_draw_offset from image->mt to irb->mt but didn't move the irb->mt replacement up before set_draw_offset). Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=44961 NOTE: This is a candidate for the 8.0 branch. I tested it on a GM965, and it seems to be working for me. Feel free to reopen if problems persist. marking dup to show the relation. |
