Can someone report on PWM in Retroid 5/Retroid Mini?

Hi everyone

A few years back I discovered a lot of Chinese phones are unusable for me because they were using heavy PWM and it made me super dizzy overtime

Yet I'm ok using Switch OLED and a few other devices

I recently tried RG556 and it's definitely unusable for me

I'm eyeing the Mini or retroid 5 but OLED worries me. Could someone be kind enough to let me know what the PWM situation on these devices is?

Is anyone else sensitive to PWM using these without problems?

Thank you
