From 2cad80cbc4775447152a631bbfcabbf8d642e833 Mon Sep 17 00:00:00 2001 From: Peter Kim Date: Fri, 11 Feb 2022 20:42:30 +0900 Subject: [PATCH] Fix incompatible swapchain format for Quest 2 When using a RGBA16 (`GL_RGBA16`, `DXGI_FORMAT_R16G16B16A16_UNORM`) swapchain format with Quest 2, no image is presented to the headset. This can occur when using the SteamVR runtime with an AMD graphics card (ex. T95374). Workaround is to move this format after the Quest 2-compatible RGBA16F formats in the candidates list so that the RGBA16F formats are chosen instead.
