Hi,
We've just upgraded for 21.1.6 to 21.2.2 and have noticed a significant sluggishness mainly in the redraw of the ribbon. I've also noticed that previously when switching between ribbon pages the new page would slide in from the left and that no longer happens. We're using SVGs for the graphics so wondering if one of the changes in that area is responsible.
I'm attached 2 videos of me switching back and forth between 2 ribbon tabs to demonstrate the difference. In the 'slow' one note that I stop clicking the mouse and it takes 5-10 seconds to catch up.
Hope you can help.

Hello Pete,
I couldn't reproduce this issue with our demos.
Could you please create a new project and copy the content of the form that is demonstrated in the videos to the new project's form? Does this issue occur with this project?
If it does, please share that project in your next comment. I will examine this behavior.
Hi Alex,
Unfortunately I’ve not been able to replicate this issue in a small test project yet. I'll spend a little more time trying to replicate it, but will need to revert to the older version and get on with other things tomorrow. We really only upgraded to get rounded corners on Windows 11…
Thank you for your cooperation, Pete. I'm looking forward to your results.
Hi Alex,
After a lot of head scratching I've figured out how to replicate the problem in a small test project.
Essentially if you have the form wide enough that the 'OfficeSearchBox' is visible then switching between tabs on the ribbon is really slow. If you narrow the window so it disappears it runs at the old/fast speed.
Hope that's enough for you to replicate the problem and fix it.

Also, I've narrowed the version down to being between 21.1.8 and 21.2.2.
Hello Pete,
Thank you for the test project. It will take us some time to examine the cause of this behavior.
