Wait...
Reading description it sounds like real bug was this: https://gitlab.gnome.org/GNOME/gnome-flashback/issues/15
So real fix is this - https://gitlab.gnome.org/GNOME/gnome-flashback/commit/028122a439f227a3c107b45d6d2a2f56b5144a8a and it is already in 3.32.0 release.
https://gitlab.gnome.org/GNOME/gnome-flashback/issues/16 https://gitlab.gnome.org/GNOME/gnome-flashback/commit/31ceaf77242e423cf27018f6e545deeb5fc154c8
That bug and commit only fixes flickering and without other patch it won't fix this bug. So both patches must be included in older releases.
