Windows update causing issues ( KB5074109 )

Featured Replies

Haven't seen this mentioned so forgive if I missed it. Recently I have had performance issues, including flickering screens in both MFS2020 and MFS2024 when they were in focus. Luckily the flickering went away in VR. After removing the windows update, flickering has gone and performance is back.

The culprit is update KB5074109 .

Not for everybody.
I installed the update on 14-01-2026, no issue at all, no screen flickering, no performance issues, no increased instability.

Same here, no issues whatsoever. I'm in the middle of a PMDG 739ER flight from BOS to SAN. Win11 is running smoothly.

Thanks so much for sharing this info @mobeans10. I had these issues after the last update but had not realized they were connected (did some HW changes at the same time).
