[Mesa-dev] [PATCH v4 1/2] wayland/egl: initialize window surface size to window size
When creating a windows surface with eglCreateWindowSurface(), the width and height returned by eglQuerySurface(EGL_{WIDTH,HEIGHT}) is invalid until buffers are updated (like calling glClear()). But according to EGL 1.5 spec, section 3.5.6 ("Surface Attributes"): "Querying EGL_WIDTH and EGL_HEIGHT returns respectively the width and height, in pixels, of the surface. For a window or pixmap surface, these values are initially equal to the width and height of the native window or pixmap with respect to which the surface was created" This fixes dEQP-EGL.functional.color_clears.* CTS tests v2: - Do not modify attached_{width,height} (Daniel) - Do not update size on resizing window (Brendan) CC: Daniel Stone CC: Brendan King CC: mesa-sta...@lists.freedesktop.org Tested-by: Eric Engestrom --- src/egl/drivers/dri2/platform_wayland.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/egl/drivers/dri2/platform_wayland.c b/src/egl/drivers/dri2/platform_wayland.c index dca099500a8..a5d43094cf3 100644 --- a/src/egl/drivers/dri2/platform_wayland.c +++ b/src/egl/drivers/dri2/platform_wayland.c @@ -258,6 +258,9 @@ dri2_wl_create_window_surface(_EGLDriver *drv, _EGLDisplay *disp, goto cleanup_surf; } + dri2_surf->base.Width = window->width; + dri2_surf->base.Height = window->height; + visual_idx = dri2_wl_visual_idx_from_config(dri2_dpy, config); assert(visual_idx != -1); -- 2.17.1 ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev

Easiest way to demonstrate the issue is to use totem with "swrast" on mesa-18.2.x (e.g. Fedora 29) under Wayland: $ LIBGL_ALWAYS_SOFTWARE=true CLUTTER_BACKEND=gdk totem Play a video and resize the totem toplevel window, the size of the EGL surface remains unchanged... Reverting that patch fixes the issue, as using a DRI driver which supports DRI2flushExtension. Nevertheless, that's a regression.

Nevertheless, that's a regression. Sorry, wrong patch, the culprit is: https://cgit.freedesktop.org/mesa/mesa/commit/src/egl/drivers/dri2/platform_wayland.c?id=a9fb331ea (or https://cgit.freedesktop.org/mesa/mesa/commit/src/egl/drivers/dri2/platform_wayland.c?id=7af6be886 cherry-picked in 18.2) And actually reverting just that part from the patch: @@ -1635,8 +1646,8 @@ swrast_update_buffers(struct dri2_egl_surface *dri2_surf) if (dri2_surf->back) return 0; - if (dri2_surf->base.Width != dri2_surf->wl_win->width || - dri2_surf->base.Height != dri2_surf->wl_win->height) { + if (dri2_surf->base.Width != dri2_surf->wl_win->attached_width || + dri2_surf->base.Height != dri2_surf->wl_win->attached_height) { dri2_wl_release_buffers(dri2_surf); Fixes the issue.

I just sent an equivalent patch to the list. I'll drop my patch. Just for patch 1, Reviewed-by: Chad Versace Tested-by: Chad Versace I don't fully understand attached_width,height. So no rb on patch 2. ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
