Dear DIALux Team,

I 'm using DIALux evo version 13, and since upgrading to this version, I've encountered a persistent display issue that impacts the visualization process. Whenever I make modifications to objects—such as cutout, room adjustments - unexpected display artifacts appear, which complicate the modeling process (as illustrated in the attached video).

To temporarily resolve this, I delete the affected object and then use the Ctrl + Z command to restore it, which fortunately clears up the display issue. This problem did not occur in version 12 before the upgrade.

Thank you for your attention to this matter.

Best regards,
