GNOME System Monitor 40 UI Issues

I don't know if you want to support GTK4, but in case you do, there's a few minor glitches.

Monitor has been updated to 40.
I suppose the "Process|Resources|File System" should look like the "About|Credits".

Similarly, the "preference" dialog of the System Monitor also looks out of place:

GNOME Photo app has similar issue:

Overall, very impressive! Big updates from GTK3 to GTK4 and we only get some minor issues! ㊗️㊗️㊗️

Update: If I didn't make the issue clear, I think the left is what it should look like, but it currently looks like the right with GTK4 for the titlebar.

Here is what the System Monitor intends to look like (but with this theme, it looks different (see the first screenshot)):
