Adreno drivers are, to be polite, "perfectible". Sometimes they just don't work at all and there's not much that can be done other that Qualcomm fixing their shit. Try to upgrade your firmware if possible. Otherwise you can try custom GPU drivers.

Tried 20 different custom drivers but none of them work. The implementation of pixel sorting in redream in works fine.

Before it was broken with Mali GPU`s https://github.com/flyinghead/flycast/issues/1356 but fixed via https://github.com/flyinghead/flycast/commit/9cc3d1030d149cf6ac9e49aa119737ed864e8ed4 Try to use old build before that fixed.

Just tried with stable v2.4, same behavior as with v2.5.

Per pixel sorting works with "turnip_24.2.0_adpkg_R19" on my sd 8 gen 3 phone

Damn it works for me, I guess you gotta find a different driver for 8gen2 and maybe try Sega rally 2(usa).chd

The USA version plays perfectly tho
