The video is indeed quite awful. There must be some very specific circumstances that lead to this situation. Opening 5 tables takes less than 2 seconds on my PC, without any significant flickering. Can you do the following?
- Update your video card driver to the latest version and check if this helps.
. - Modify the shortcut and add the DebugSQL parameter. For example:
"C:\Program Files\PLSQL Developer\plsqldev.exe" DebugSQL
Reproduce the problem and send me the debug.txt file that is generated in the PL/SQL Developer directory or in the %APPDATA%\PLSQL Developer directory (e.g. C:\Users\<User>\AppData\Roaming\PLSQL Developer).
