From b9d4654fcaeb0313845f221135f4236c24ad2248 Mon Sep 17 00:00:00 2001 From: Matthias Clasen Date: Thu, 10 Sep 2020 13:55:16 -0400 Subject: [PATCH] vulkan: Fix swapchain creation We end up with a surface that has size 0x0 at the time we create the Vulkan context, and that is a size that Vulkan doesn't like, so ensure we request at least 1x1.
