From 99914164455a589756186085b9b66d23f1318ee2 Mon Sep 17 00:00:00 2001 From: Carlos Garnacho Date: Tue, 20 Nov 2018 18:06:38 +0100 Subject: [PATCH] wayland/egl: Ensure EGL surface is resized on DRI update_buffers() Fullscreening and unfullscreening a totem window while playing a video sometimes results in the video subsurface not changing size along. This is also reproducible with epiphany. If a surface gets resized while we have an active back buffer for it, the resized dimensions won't get neither immediately applied on the resize callback, nor correctly synchronized on update_buffers(), as the (now stale) surface size and currently attached buffer size still do match. There's actually 2 things to synchronize here, first the surface query size might not be updated yet to the wl_egl_window's (i.e. resize_callback happened while there is a back buffer), and second the wayland buffers would need dropping if new surface size differs with the currently attached buffer. These are done in separate steps now. v2: Added the 'Fixes' tag https://bugzilla.redhat.com/show_bug.cgi?id=1650929 Fixes: a9fb331ea7d ("wayland/egl: update surface size on window resize") Signed-off-by: Carlos Garnacho Tested-by: Bastien Nocera --- src/egl/drivers/dri2/platform_wayland.c | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) diff --git a/src/egl/drivers/dri2/platform_wayland.c b/src/egl/drivers/dri2/platform_wayland.c index c3ca1b6f7bc..3025e34ba63 100644 --- a/src/egl/drivers/dri2/platform_wayland.c +++ b/src/egl/drivers/dri2/platform_wayland.c @@ -637,10 +637,8 @@ update_buffers(struct dri2_egl_surface *dri2_surf) struct dri2_egl_display *dri2_dpy = dri2_egl_display(dri2_surf->base.Resource.Display); - 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); + if (dri2_surf->base.Width != dri2_surf->wl_win->width || + dri2_surf->base.Height != dri2_surf->wl_win->height) { dri2_surf->base.Width = dri2_surf->wl_win->width; dri2_surf->base.Height = dri2_surf->wl_win->height; @@ -648,6 +646,11 @@ update_buffers(struct dri2_egl_surface *dri2_surf) dri2_surf->dy = dri2_surf->wl_win->dy; } + 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); + } + if (get_back_bo(dri2_surf) < 0) { _eglError(EGL_BAD_ALLOC, "failed to allocate color buffer"); return -1; -- 2.20.1
