a strange change, it duplicates the "icons" of this corner.

when I put the mouse in the upper right corner of the window the eM Cliient presents a strange change, it duplicates the “icons” of this corner.

Hello Afonso,
would you mind taking a screenshot of this problem for me? I am afraid we haven’t encountered this issue before. Do the duplicated icons stay for a period of time or do they disappear again? Is there an error message that accompanies this? Please share more information about this problem. Thank you.

Best regards,
Olivia
