From d17165f08b46628360b2400975ea2770c40826a1 Mon Sep 17 00:00:00 2001 From: Luke Jones Date: Wed, 6 Sep 2023 02:20:04 +1200 Subject: [PATCH] Enable vulkan presentation on Intel Mesa >= v21.2 (#4110) Due to an issue with Mesa versions less than 21.2 presentation on Vulkan was forced to Nvidia only. This in itself brought new issues around the Nvidia driver specfic format modifers. As of Mesa 21.2 the Intel vulkan issue is fixed. This commit enables presentation on versions 21.2 and above for Intel.
