Created attachment 91230 [details] Screenshot of Weston with Wayland backend Running weston-launch from a terminal results in a corrupt display. I'm running Enlightenment, which includes a wayland compositor as part of the X compositor, so I did more testing inside that. Running weston with the x11 backend is fine, but running it with the wayland backend displays the same corruption as the drm backend; log below of running it both ways, see attachment for a screenshot of the corruption. Running weston-simple-shm is fine, but weston-simple-egl shows the same corruption. wayland and weston are both freshly built from git master, has happened consistently since I've been trying, prior to v1.2. Only thing in weston.ini is the xwayland module. Running an up to date Arch Linux system, and have found one other Arch user with the same issue, running the same video hardware. All other info should be in the log. dnewgard@Scimmia ~/.config % weston --socket=wayland-1 --backend=x11-backend.so Date: 2013-12-27 CST [10:24:55.662] weston 1.3.91 http://wayland.freedesktop.org/ Bug reports to: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=weston&version=1.3.91 Build: 1.3.91-6-g24dff2b-dirty compositor: Clean up view output move and destroy listeners (2013-12-19 21:52:09 -0800) [10:24:55.662] OS: Linux, 3.12.6-1-ck, #1 SMP PREEMPT Fri Dec 20 14:01:51 EST 2013, x86_64 [10:24:55.662] Using config file '/home/dnewgard/.config/weston.ini' [10:24:55.662] Loading module '/usr/lib/weston/x11-backend.so' [10:24:55.671] initializing x11 backend [10:24:55.672] Loading module '/usr/lib/weston/gl-renderer.so' [10:24:55.690] Using gl renderer [10:24:55.690] launching '/usr/lib/weston/weston-keyboard' [10:24:55.705] Chosen EGL config details: RGBA bits: 8 8 8 0 swap interval range: 0 - 0 [10:24:55.715] EGL version: 1.4 (Gallium) [10:24:55.718] EGL vendor: Mesa Project [10:24:55.718] EGL client APIs: OpenGL OpenGL_ES OpenGL_ES2 [10:24:55.718] EGL extensions: EGL_WL_bind_wayland_display EGL_KHR_image_base EGL_KHR_image_pixmap EGL_KHR_image EGL_KHR_reusable_sync EGL_KHR_fence_sync EGL_KHR_surfaceless_context EGL_NOK_swap_region EGL_NV_post_sub_buffer [10:24:55.718] GL version: OpenGL ES 2.0 Mesa 10.0.1 [10:24:55.718] GLSL version: OpenGL ES GLSL ES 1.0.16 [10:24:55.718] GL vendor: X.Org R300 Project [10:24:55.719] GL renderer: Gallium 0.4 on ATI RV515 [10:24:55.719] GL extensions: GL_EXT_blend_minmax GL_EXT_multi_draw_arrays GL_EXT_texture_filter_anisotropic GL_EXT_texture_compression_dxt1 GL_EXT_texture_format_BGRA8888 GL_OES_depth24 GL_OES_element_index_uint GL_OES_fbo_render_mipmap GL_OES_mapbuffer GL_OES_rgb8_rgba8 GL_OES_standard_derivatives GL_OES_stencil8 GL_OES_texture_3D GL_OES_texture_npot GL_OES_EGL_image GL_OES_depth_texture GL_OES_packed_depth_stencil GL_EXT_texture_type_2_10_10_10_REV GL_OES_get_program_binary GL_APPLE_texture_max_level GL_EXT_discard_framebuffer GL_EXT_read_format_bgra GL_NV_fbo_color_attachments GL_OES_EGL_image_external GL_OES_vertex_array_object GL_ANGLE_texture_compression_dxt3 GL_ANGLE_texture_compression_dxt5 GL_EXT_texture_rg GL_EXT_unpack_subimage GL_NV_draw_buffers GL_NV_read_buffer GL_EXT_map_buffer_range GL_OES_surfaceless_context [10:24:55.719] warning: EGL_EXT_buffer_age not supported.

Could have something to do with resolution. I just loaded up weston-terminal and it looked the same, but as I resized it, the angle of the vertical lines changed and if I got it just right, it looked fine. Starting weston with the wayland backend, the log reports "Creating 1024x640 wayland output at (0, 0)", but Enlightenment reports the resolution as 1100x737. Resizing that window doesn't help, though. Neither does resizing weston-simple-egl. I would blame Enlightenment if it wasn't that the drm backend looks exactly the same.

Resizing that > window doesn't help, though. Neither does resizing weston-simple-egl. weston-simple-egl is not resizable, and I think the Wayland backend is neither. You'd have to set the size in advance. What you describe does sound and look like "bad pitch", which would likely be a 3D driver issue. Btw. did you notice, that some of your runs use the ATI RV515 renderer while the other one uses llvmpipe (software) renderer for OpenGL? That might actually help to narrow down the bug, if you do that intentionally, and do not accidentally e.g. mix different Mesa versions, for instance what Weston uses vs. your hosting X server.
(In reply to comment #3) > weston-simple-egl is not resizable, and I think the Wayland backend is > neither. You'd have to set the size in advance. Oops, sorry, looks like they nowadays do have resizing support.
Actually I hadn't noticed that, interesting. What's more, the wayland backend is running llvm pipe while the drm backend is running RV515, both of which have the problem which makes me think it's not specific to the renderer. The x11 backend that works is also running RV515. All of the logs were run within an hour of each other with no changes on the system in between. As for resizing, I just tried it again, when resizing weston-terminal, it's actually the terminal itself being resized where the others I was resizing with the WM's decorations. In the latter case, it was just stretching things.
I believe this would be an error in the GBM implementation, but either way this should be fixed now since others have managed to run it fine on similar hardware.
