The display of Wireshark is strange on a 4K monitor
When I press the menu while using a 4K monitor, the screen is displayed off-center. There were also cases where it did not function correctly depending on the situation.
Could you add the info from the Wireshark -> Help -> About Wireshark -> Wireshark dialog. Hint use the "Copy ..." button to copy the text for pasting into your response.
