Window capture of 2 different videos (on diff browser windows) on 2 instances of OBS = only 1 video displays

[dbgt]

Ok, so i am trying to record 2 videos simultaneously (for ex. youtube) using 2 instances of OBS and window capture on each browser window playing different videos, but OBS only displays the video of the window that is on top, the other video (which is in another browser window) does not plays on the other instance of OBS (even though it is of course playing in the browser window), theres just a black screen on OBS if I use chrome or a gray screen if microsoft edge is used. I know it is possible to do this because I was doing exactly this before with microsoft edge, but it seems that due to a recent update of the browser it is now not possible

The problem is always the browser window that is not on top:

browser window with video A on top = plays fine in 1 instance of OBS
browser window with video B under the other browser window = black screen or gray screen on the other instance of OBS

If i click on the browser window with video B and thus it comes on top, then the gray or black screen will disappear and the video will immediately display on OBS, but the other video which was playing fine on the other instance of OBS will now display a black or gray screen...

Why this happens and how can i fix it? I already searched everywhere but i can only find different issues, i tried their solution; like disabling hardware acceleration but i get the same result.

I am using a desktop with windows 10

Modern browsers stop displaying video in the background to save power. In Chrome you can turn it off at chrome://flags/#calculate-native-win-occlusion, not sure about others.

OMG! Youre a wizard! I just tried it and it worked! I searched for days and hours upon hours with no results, and you solved it in 2 sentences..... I am very grateful, thank you so much! I would have never been able to figure this by myself.
