I cannot reproduce your problem.
What I did can be seen in the attached demo.

1. Unzip it and run it.
2. right click into the edit at the bottom

On my Windows 10 x64 VM this opens a TJvPopupMenu with 2 entries, both call ShowMessage each and I do not see any flicker. I can click them and they bring up their message each.

=> how does your test case differ?
