From 481b210c0d035d3de36dc7845802135d90d25a8b Mon Sep 17 00:00:00 2001 From: ameerj <52414509+ameerj@users.noreply.github.com> Date: Thu, 23 Dec 2021 20:55:48 -0500 Subject: vk_texture_cache: Fix invalidated pointer access The vulkan ImageView held a reference to its source image for rescale status checking. This pointer is sometimes invalidated when the texture cache slot_images container is resized. To avoid an invalid pointer dereference, the ImageView now holds a reference to the container itself. --- src/video_core/renderer_opengl/gl_texture_cache.cpp | 2 +- src/video_core/renderer_opengl/gl_texture_cache.h | 4 +++- src/video_core/renderer_vulkan/vk_texture_cache.cpp | 15 +++++++++++---- src/video_core/renderer_vulkan/vk_texture_cache.h | 5 ++++- src/video_core/texture_cache/texture_cache.h | 3 ++- 5 files changed, 21 insertions(+), 8 deletions(-) (limited to 'src/video_core') diff --git a/src/video_core/renderer_opengl/gl_texture_cache.cpp b/src/video_core/renderer_opengl/gl_texture_cache.cpp index 14e6522f2..3c1f79a27 100644 --- a/src/video_core/renderer_opengl/gl_texture_cache.cpp +++ b/src/video_core/renderer_opengl/gl_texture_cache.cpp @@ -1047,7 +1047,7 @@ bool Image::ScaleDown(bool ignore) { } ImageView::ImageView(TextureCacheRuntime& runtime, const VideoCommon::ImageViewInfo& info, - ImageId image_id_, Image& image) + ImageId image_id_, Image& image, const SlotVector&) : VideoCommon::ImageViewBase{info, image.info, image_id_}, views{runtime.null_image_views} { const Device& device = runtime.device;
