Random black screen just in online racing?


Got lurked by Boonatix' latest article, so just re-joined online ACC racing this morning.
Both in qual and race I discovered black screen, the first about 5 sec, the latter in race essential for about 15 secs.
I've never discovered this during offline racing.

Online qual, about 10 min ingame racing, sudden 5 secs of black screen
Online race, ditto, here sudden 15 secs of black screen.

Running ACC in resolution: 2560x1440p @ 165Hz
Using a Sapphire RX 580 Nitro+ standard clockings and a Gigabyte G32CQ monitor, connected with optical cable.
Having no problems with that setup in other sims or offline ACC racing for a long time.

AMD Radeon Software: 21.8.1 (yes I see, there's a 21.8.2 update, but this version have been working stable).

Just discovered I have In-Game Overlay enabled in Radeon Software- could this be the cause?

From logfile (not exactly sure if that's the time of the black screen freeze);

OK so now did an online race, having made the following changes
- AMD Radeon Software upgrade to 21.8.2
- Disabled In-Game Overlay in Radeon Settings
- Lowered update frequenzy from 165 Hz to 60 Hz (still 1440p)

That made a stable online race without any black screen/freeze or other halts.
I can stick with this.
