            @jsulm

            I tried removing the taskbar of Raspbian and running it, and the same symptoms appear.
            Is there any other way?

              I tested the same in Ubuntu OS, but the same phenomenon as in Raspbian does not appear.
              For me this is a very important issue.
              You may need to change your development direction and environment.

                @IknowQT What graphics environment and window managher do you use?
                Do you use X server?

                    @IknowQT You should know what you installed.
                    What does

                    ps ax | grep X
                    

                    output?

                        @IknowQT So, you have X server running and you're using LXDE desktop environment.
                        You could try with some other desktop environment to see whether it behaves in the same way (XFCE for example).

                          Are you saying you need to test on a different version of the OS?

                            @IknowQT No. I did not say anything about a different OS version. I only suggested to test with another desktop environment (window manager). On Linux there are many different desktop environments...

                              Even after changing the window manager to openbox, the flickering phenomenon appears.

                              *raspberry board version
                              pi4 model b
                              *raspberry os version
                              buster 5.10.75-v71+

                              Are there any window managers you can recommend for my development environment?
