Vulkan: Prefer MSRTSS for QCOM devices The feature flag `preferMSRTSSFlagByDefault` was originally added to avoid allocating extra memory if the images are created with the MSRTSS flag by default. If it is disabled, the image will be recreated with the said flag only if it bound to an MSRTT framebuffer. * preferMSRTSSFlagByDefault is now enabled for QCOM driver versions beyond 0777.0.
