SUMMARY When changing the name of a FORM window, a <2> is appended to the end of the new form name. It doesn't happen in Windows, Linux Mint or XFCE. STEPS TO REPRODUCE 1. Change name of FORM 2. Run Lazarus app and observe new form window 3. OBSERVED RESULT <2> is appended to the FORM name. EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.18 KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION Lazarus 2.06
Lazarus is a Free Pascal IDE
Lazarus changes the window title, then opens a new window with the same title (because it thinks attributes have changed), then closes the original window. It should only do one of these steps, not both. *** This bug has been marked as a duplicate of bug 209648 ***
