      [5658:1213/232023.441362:ERROR:gbm_wrapper.cc(253)] Failed to export buffer to dma_buf: No such file or directory (2)

      I’m not sure whether this error is related to your symptom but refer to this.
      https://forum.magicmirror.builders/topic/18076/failed-to-export-buffer-to-dma_buf-no-such-file-or-directory

      And for ;

      [5658:1213/232033.074222:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 1 times!

      It also seems related to the GPU/GL issue of electron/chromium.
      https://github.com/electron/electron/issues/32760

      Hmmm, for those issues, I cannot help.

      If you find something other from the log, report it again.

        Maybe there would be some memory leaks on the chromium.
        Can you test it again with more simple animations?(Just fadeIn, fadeOut) Some version of Chromium is known for possible memory leaking on transitions.

          And, your log is just backend log, I need front-end log.
          You can see front-end log by;

          • installing MMM-LogExt
          • Or, dev-console of your MM screen, not terminal. (with npm run start:dev, you can see dev-console panel on your MM screen.)

              I have changed the animations. New: fadeIn/fadeOut
              I have installed MMM-LogExt.
              MagicMirror is running and I will keep an eye on it. As soon as it stops running correctly, I will post the logs.
              Thank you

              Is MMM-LogExt working correctly or do I need to adjust something?

                Log says nothing suspicious. I suspect Chromium graphic memory leak issues due to last parts of error-log.
                In that case, I have nothing to help. Sorry.

                  Thanks anyway.

                  Would you say it’s the Pi version? Software/hardware version? Could this be fixed with a Chromium update in the future?

                    Very strange. I have created a third scene. Now it is already running for several hours.

                      I have the same problem, after about 1 hour there is no change of modules.
                      I also want a constant change of MMM-iframeReload and MMM-iframeReload2 module

                        I researched about that error message.
                        The error messages seemed not to be the module or logic issue but the GPU/System issue. (Usually in -nix machines about graphic drivers.)

                        However, I’m not sure the error message is related to your symptom actually. There is a chance these two things could be independent.

                        What I suggest for the test is;

                        • use simpler animation effects or no animation.
                        • give a longer life for the scene.
                        • Remove all other 3rd party modules, except default modules (clock, …)

                        If it helps, we can progress from it anyhow.
                        But if not; I think I rarely have things to do.
