From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx> With the current code we just reallocate the compressed FB at every FBC update: we have X in one frame, then in the other frame we need X again, but we check "needed < have" instead of "needed <= have". v2: Rebase after Jani addressed the other problems described in v1.
