Using the same AV1 videos but in HD resolution instead of FullHD, I
don't have any problems or even slowdowns in playback and reverse

without these configurations: all is fine in both cases.
Anyway, my VM has always been set up with 8GB of RAM (out of 32
physical) and 4c/8t for the CPU (out of 8c/16t physical), but
apparently that's not enough to support FullHD.
may be problem with 32-bit case is limited _virtual_ address space - no more than 4gb, and some of it eaten by kenel mapping pci devices and such. Ironically so-called PAE linux kernel can address more physical ram than 4gb, yet individual processes limited to some 3gb... or even less (depend on kernel configuration, vm_split I think...)
On my system (Arch Linux 64-bit; KDE), I've tried compiling just the
patch (without export and --disable-dav1d) and it works without
problems. However, with FullHD videos, playback is smooth but reverse
playback has some framerate drops.
Sorry for wasting your time behind false problems.
well, they not false just rare (due to limited 32-bit testing). Not like we can do much about memory exhausting errors.. but this might deserve some footnote.
