LG 27GM950B screen flickering/blackout

Is anyone else running into flickering issues with this monitor, or issues where it goes black for a milisecond and comes back again? it's driving me insane!!
My first monitor (same model) developed a line on the left side, which went away and came back. I returned it, now I am with second one which worked fine for a day, but I think when I work for a full workday on it, it heated up (just a theory) and then I started seeing screen tearing and other flickering, especially when I switched to game mode for testing on PC. Each time this happens, I have to unbox/re-pack, mount/unmount from desk, re-route cables at the back of my desk and I want to avoid doing that if possible and keep this monitor.

I tried all the usual steps:
Went from monitor directly to Macbook (USB-C/HDMI)
Went from monitor directly to PC
Dropped one monitor to see if that makes a difference (I have two monitor setup)
Changed cables from USB-C, to Displayport (on PC) and then finally HDMI to both PC and Macbook
Installed LG switch app and upgraded the firmware to 3.06

Anyone else with similar issues?

LG 27GM950B-B Daisy chaining with Apple Display XDR

So, I was looking for this before purchasing anything and couldn't find anything. So here it is, I am going from M4 Max macbook to Apple Studio XDR to LG 27GM950B-B. Both 5k, 120 Hertz (XDR) and 144 Hertz (LG). Also connected USB-A device (Stream deck) to LG and its working fine too. I guess I am surprised because I wasn't expecting apple to play nice with other monitors.

Also, True Tone is now applying to both XDR and LG.

Are there any downsides to this setup that I am missing?

Please let me know if you have any questions also.

New LG 27GM950B had a green line that vanished, should I return?

I unboxed a new monitor, carefully setup and zero damage off course. After 5-10 minutes of testing cables and all, two green lines showed up in the middle, then one stayed after few minutes and finally that single line became really vague and now its gone. It was there with all sorts of connection cables (hdmi, display, usb-c).

My question is, is this normal and sometimes pixels/lines get fixed by themselves or down the road I will run into issues with this monitor. This is my very first monitor, which is THIS expensive!

Please advise!
