From eaf6884621661288624fc060974c3aa485771324 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Fri, 30 Nov 2012 17:41:02 +0200 Subject: egl/wayland: Don't invalidate drawable on swap buffers We used to invalidate the drawable after a call to eglSwapBuffers(), so that a wl_egl_window_resize() would take effect for the next frame. However, that leads to calling dri2_get_buffers() when eglMakeCurrent() is called with the current context and surface, and a later call to wl_egl_window_resize() would not take effect until the next buffer swap. Instead, add a callback from wl_egl_window_resize() back to the wayland egl platform, and invalidate the drawable only when it is resized. This solves a bug on wayland clients when going back to windowed mode from fullscreen when clicking a pop up menu, where the window size after this would be the fullscreen size. Note: this is a candidate for stable branches.
