What do you think about these tests ? There have been several revisions of the libts.tcz. Which you can review 'here' (https://github.com/ralph-irving/tcz-libts).
I had a similiar problem with my original rpi 7" screen that was caused by the power adapters. Turns out both of my 2.5A power bricks were the culprits, which really sucks since that was the first thing I swapped after I noticed the problem. I swapped in 2 different rpis, same problem. Put back in the original rpi and swapped the hat dac and still no luck. Then I tried a 2A PS with a ferrite core molded into the wire and the "ghosting" was gone. I've been using a 'different fork' (https://github.com/veo-labs/tslib) of kergoth's tslib, so I've created a new libts.tcz from the https://github.com/kergoth/tslib sources which includes the debounce module for you to try. For now it has the default ts.conf from the distribution and works with my rpi touch screens. I don't have either of your screens to test with.
