From ac39648426f6523b010eb3cefa75d9bb2cbf577f Mon Sep 17 00:00:00 2001 From: Romain Vimont Date: Mon, 8 May 2023 18:16:38 +0200 Subject: [PATCH] Accept texture failures When the scrcpy window is minimized on Windows with D3D9, texture creation and update fail. In that case, do not terminate scrcpy, but store the pending size or frame to update to retry on the next update or rendering.
