It's fully reproducible.
I attached a project that has 100% reproducibility. Expand the attached file in a new directory. I named mine "PopupBug". Extract the files in that directory. Once the files are extracted, the following steps are required:
1. open winunits.lpi in the windows subdirectory and compile that project. no need to change any settings, just compile/build.
2. open _zydis.lpi in the Zydis subdirectory and compile that project. no need to change any settings, just compile/build.
3. open cds.lpi in the directory you created where you extracted the archive and compile/build it. Before you can successfully run the program you need to set the "run-run parameters->command line parameters" to be the path to a 32bit executable. Any 32 bit executable will do. I left the value I use there as an example.
Once you've set the value, simply press F9 to run the program. It will break automatically. Once it has reached the break, you'll need to scroll up a bit to the instruction "ZydisDecoderDecodeFull", hover over zi_operands and you'll get the nice looking yellow popup. after that hover over zi_decoded_instruction and you'll get the grey popup.
That's it. (this project only runs in 64 bit because only the 64 bit zydis dll is included in the archive.)
Anything else I can do, just let me know.
