From 3c6ef765af9b946240cedf053e593c0fc86a3f01 Mon Sep 17 00:00:00 2001 From: CamilleLaVey Date: Thu, 9 Oct 2025 21:37:27 +0200 Subject: revert [vk] Fast UBO: fix tracking, resize heuristics, add debug guard (#2695) (#2706) revert [vk] Fast UBO: fix tracking, resize heuristics, add debug guard (#2695) Well, stuff showed up after testing phase, that showed us this change break SMO and some mods after being merged directly into master, we will keep stuying why happens this and add a better handling later.
