From 58ea90f8032912b41e753a95089ba764fcc6446a Mon Sep 17 00:00:00 2001 From: Dongwon Kim Date: Mon, 24 Jul 2023 17:11:31 -0700 Subject: [PATCH] ui/gtk: set scanout mode in gd_egl/gd_gl_area_scanout_texture MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Fixing a regression (black screen) caused by a commit 92b58156e7 ("ui/gtk: set scanout-mode right before scheduling draw"). The commit 92b58156e7 was made with an assumption that the scanout mode needs to be set only if the guest scanout is a dmabuf but there are cases (e.g. virtio-gpu-virgl) where the scanout is still processed in a form of a texture but is not backed by dmabuf. So it is needed to put back the line that sets scanout mode in gd_egl_scanout_texture and gd_gl_area_scanout_texture.
