XA2 Dual Sim - Red Screen Bug when opening display lock (Tint overlay faulty)

REPRODUCIBILITY (% or how often): After some time of idling
BUILD ID = OS VERSION (Settings > About product): 3.4.0.24 and 3.4.0.22
HARDWARE (Jolla1, Tablet, XA2,…): Sony Xperia XA2 Dual-Sim
UI LANGUAGE:Fin
REGRESSION: (compared to previous public release: Yes, No, ?): Last used SFOS as daily phone in January 2020, newest version

DESCRIPTION:
Tried early access 3.4.0.22 and after short use without Sim card (only wlan) the problem started to show up: Waking up screen from blank screen by pressing side button, screen lights up with red color and thats all. Shutting down screen doesn’t help. Have to press lock button long time to get XA2 to power down and then startup again.
Now today I started using XA2 as my primary phone has speaker issue. Upgraded to 3.4.0.24. Now have encountered this once already.
Cannot find any others having this same issue?

It seems to me that phone and os is working still, when the screen is totally red.

PRECONDITIONS:

STEPS TO REPRODUCE:

  1. idling some xx min time
  2. opening tint overlay app !

EXPECTED RESULT:
Wake up screen to display lock view

ACTUAL RESULT:
100% red colored screen

ADDITIONAL INFORMATION:
Have storeman, patchmanager but not any patch in use. No phonebook or battery overlay installed.

Interesting. The problem is with SFOS3.4 and Tint overlay program from openrepos. Learned this at the same time as writing this bug report
