Ribbon window glitches when resizing and sometimes the close button does not work

Also when minimize and maximize the ribbon window, the ribbon window becomes small and the big.. It is like going to a predefined size and go to the desired size and this causes this flickering.

Hi Daniel,

Our developers tried to reproduce this on multiple machines but are not seeing any problems.  We are all on Windows 11.

Can you answer:

• When did you first start noticing this?
• Please confirm the Actipro WPF Controls version you are on.
• Are you using our classic Ribbon product or the new Bars Ribbon?
• Can you reproduce this in any of our samples?  If so, which one and how?
• Which Windows version are you on?
• Which .NET version does your app use?

Hi!

I will make more tests to be sure but at the moment I could reproduce with 23, 24 and also 25 versions.

Currently I am using 25.1.1, Ribbon controls, I have windows 11 and the app uses .Net Framework 4.8.

I could not reproduce on the actipro samples.

I will do more tests! Strange thing is that when I use a normal WPF window instead of the RibbonWindow I have no issues.

Kind regards,

Daniel

Hi!

The window is even more flickery when using the left top corner to resize.

One mention also, I have like 11 tool windows: 2 on the bottom and 9 on the right (4 right top side, 5 right bottom side). But still with normal WPF window the resize is way smoother.

Kind regards,

Daniel

Hi Daniel,

For something like this, the best thing to do would be to create a new simple sample project that shows it happening and send that to our support address so we can reproduce it here and debug with that.  Mention this thread in your email and give any steps necessary to reproduce.  Be sure to exclude any bin/obj folders from the .zip you send so the email doesn't get spam blocked.  Thanks!
