About that felt problem (the weird space/gap at the edges of the table skin). The problem is surprisingly in Ordinary theme's gx.ini. I deleted the Ordinary folder once again and only replaced gx.ini there and it looked bad right after. So that was 100% the reason.
It looks like PokerStars has added something new in Ordinary's/Hyper simple's gx.ini and that was causing it. What made it also weird was that with my gx.ini there actually were some tables that worked, I found out just recently, but none of the cash tables and tournament tables looked as they should. Then I clicked on some guy via player search feature and by accident I saw his 90man SNG table looking normal.
But yeah all is OK now, except that I need to redo that gx.ini and add every line I edited/added back in it, sigh.
Wow. This is how much they actually added in the gx.ini, marked blue so about 2x more text than before. On the left side is the new gx.ini and text marked as blue is almost all new excluding few lines of [~images], but new stuff there too.
