Menu control drop-down menus were not displayed in the correct position for the first time

Dear Sir

When I using the demo winform (version. 2025 Q1), all the menu drop-down menus were not displayed in the correct position for the first time. Include the controls of menus and ribbon bar in hidden mode. Could you please checked the display problem. Is there any solution to prevent the error from showing? Thanks.

Hi Vance Chiang,

Thank you for the provided images.

It seems to me that the examples from the images are shown on an HDPI monitor. Can you share the scaling option on the monitor in which the reported behaviors are observed? Can you also create a video with the steps so that I can try to follow them on my side and reproduce this?

Hi Dinko

My NB connected one monitor with HDMI to extend the screen. The NB screen resolution is 2560 x 1600, and the ratio is 150%. The screen resolution of connected moniter is 1920 x 1080, and the ratio is 125%.

About the video, I upload the file on cloud. And the links at here.

Thank you for the additional details. I was able to observe the described behavior when the main monitor has HDPI. This is already logged in our Feedback Portal. You can try to disable the improvements by setting the RadControl.EnableRadAutoScale static property to false.
