UPDATE :
Very very good news, it seems we find the rigin of these problems !!!!!!
We hope please Mr @Catsxp will make the necessary to fix these problems, thanks !!
But to quickly summarize the solution to these problems:
Chromium 136.0.7071.1 does not have these issues:
https://github.com/e3kskoy7wqk/Chromium ... 6.0.7071.1
However,
Chromium 136.0.7083.1 does have these issues:
https://github.com/e3kskoy7wqk/Chromium ... 6.0.7083.1
here the explanation of the solution, i copy paste the solution found by Mr. @e3kskoy7wqk the developer of Chromium-for-windows-7 :

"-It seems I have to use a binary search to find the problem. Over the next period of time, I will build many versions between 136.0.7071.1 and 136.0.7083.1 to identify which specific commit caused the issue. Since I cannot reproduce this problem, I need @trimechee's help to test. @rafaelmattos1969, @idontyboi, if you're still affected by this issue, you're welcome to assist with testing these builds as well.
@trimechee First, I need to confirm whether the issue starts appearing from version 136.0.7083.1 (i.e., 136.0.7071.1 does not have this issue, but 136.0.7083.1 do)?
-Good news!!!! I'm going to cry with joy and happiness!!!! I just installed the zip version of Chromium 136.0.7071.1, and Chromium 136.0.7071.1 does not have these issues !!!!!
Bravo Mr. @e3kskoy7wqk

and thank you so much for finding the source of the problem!!!!
I really can't believe my eyes. I really thought it was the end of Chromium on Windows 7! So yes, Chromium 136.0.7071.1 has no display issues, everything is normal, there is no problems in Chromium 136.0.7071.1, the content of web pages, menus, etc., is displayed correctly!!!!
Now I have to delete the zip version of Chromium 136.0.7071.1 and install version 136.0.7083.1 to see if any problems appear !!!
Obviously we share this excellent news with Mr @win32ss and we thank him so much for his precious help and ideas to find solutions to this exciting mystery
......
another good news!
Mr. @e3kskoy7wqk, exactly as you thought, I just installed Chromium zip version 136.0.7083.1 and the display issues are back again : unreadable web page content, unreadable menu...
while Chromium zip version 136.0.7071.1 does not have any issues!
Well done, Mr. @e3kskoy7wqk!
you have accomplished the amazing feat of finding the source of this problem and I assume now you'll compare the code of these two versions of Chromium to find the source of these problems! We also inform Mr. @win32ss's about the progress in resolving this problem, hoping he will give us his important opinion about the origin of this problem, thanks !"
here the 2 chromium versions :
