Switched to TLSF as the default algorithm - in default pools, custom pools, virtual blocks. Removed generic and buddy algorithm. Removed flags: VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT, VMA_POOL_CREATE_TLSF_ALGORITHM_BIT, VMA_VIRTUAL_BLOCK_CREATE_BUDDY_ALGORITHM_BIT, VMA_VIRTUAL_BLOCK_CREATE_TLSF_ALGORITHM_BIT.

<p >If your bug goes away after enabling margins, it means it may be caused by memory being overwritten outside of allocation boundaries. It is not 100% certain though. Change in application behavior may also be caused by different order and distribution of allocations across memory blocks after margins are applied.</p>
<p >Margins work with all types of memory.</p>
<p >Margin is applied only to allocations made out of memory blocks and not to dedicated allocations, which have their own memory block of specific size. It is thus not applied to allocations made using <a class="el" href="group__group__alloc.html#ggad9889c10c798b040d59c92f257cae597a3fc311d855c2ff53f1090ef5c722b38f" title="Set this flag if the allocation should have its own memory block.">VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT</a> flag or those automatically decided to put into dedicated allocations, e.g. due to its large size or recommended by VK_KHR_dedicated_allocation extension.
