Kirby Star Allies - Graphical bugs occuring randomly

Hi :wave:

I’ve been playing Kirby Star Allies since few days, but I’m struggling with some graphical bugs when playing. These seems to occur randomly when playing.

Switching display mode ( TV mode; Switch’s screen mode) seems to temporaly fix the bug, but it can occur in any display mode.

Here is a screenshot of the bug :

Does anyone have an idea about this ?
Thanks !

Try either updating the GPU driver, or downgrading to 472.12, you can expect different behaviour with those two, depending of the game.
Also, just in case, test with asynchronous shader building disabled.

Thanks for help,

I’ve disabled the asynchronous shader building, but that didn’t fixed the problems. ( Test without modifying GPU’s driver )

Also, upgrading or downgrading the GPU driver hasn’t any effect on the bug, it still occur, randomly

Does it change if you disable all mods?

I’ve disabled all mods , but that don’t seems to avoid the bugs ( Tested with GPU driver v511.79 )

The disabled mods were “60FPS” and “Update V4.0.0” ( it seemed a bit more laggy than with the mods enabled )

Here is the video to get a better view of the problem : [Yuzu] Kirby Star Allies TEST without Mod or Update (GPU 511.79) - YouTube

This could also be due to your hardware (like your gpu). Faulty things can happen. This does look kind of like artifacting not just emulator issue.

Could be, but I can’t try with a different hardware
Does someone already had a similar issue related to hardware problems ?

Nobody has recently had issues like you presented above. It is likely particular to your hardware atm. Could try reinstalling your driver for gpu or re-seating it in the pcie slot of pc.
