Bug 1787520 - Avoid invalidating render targets on Mali-G78 devices. r=gfx-reviewers,jrmuizel
On the Pixel 6 family devices we are seeing frequent image corruption issues on some websites, which started following the Android 13 upgrade. This can be avoided by not invalidating the no-longer-needed render targets at the end of each render pass. This is only an optimization anyway, so is safe to skip. The Android 13 update upgraded the Mali driver from version v1.r32p1 to v1.r36p0. As we did not encounter this bug prior to the Android 13 update, this patch only applies the workaround on driver versions v1.r36p0 and above. It's possible other GPUs than the G78 are also affected, but for now we limit the workaround to just this GPU. We can re-evaluate if and when we receive bug reports from users on other GPUs.
