Can you please provide a screen recording of the issue you are seeing? I've created an account on the site and tried some of the pages and they all seem to be loading fine.

This is on a Windows 10 surface book with Chrome 62.0.3202.94
Hi,
i have uploaded a video as RAR Archive.
You need a file in the Controlpanel. I have already uploaded a file in your test account.

On this page the problem appears when you zoom to 110% with a screen size of 1920x1080 in Chrome: https://controlpanel.aimondo.com/repricing/select_file/

Over to the layout and paint teams to analyze. I cannot reproduce myself of a surface book adjusted with that screen resolution and zoom factor. However it is clear in the video that stuff is moving around and layouts are getting adjusted which causes the snapping back and forth.
Thanks for your quick reply. In our company almost everyone had this problem. I just looked into my private laptop and I didn't have the problem, but on my computer the problem persists. It must be Windows 10 installed, the icons in the taskbar must be normal sized. Display zoom at 100% and Chrome at 110%, preferably on a 24 inch display (1920x1080).

Unable to reproduce the issue on the reported version 62.0.3202.94 on Windows 10.

As per comment#5, I request someone from respective team look into it.

Thanks!
Hi, I've seen that you've created a test account again. I have written a workaround for this bug which I have now taken out again. But as I said before, you have to upload a file in our ControlPanel. I have uploaded a file for you now. You can look again: https://controlpanel.aimondo.com/repricing/select_file/

Please note my comment 6.

Re comment #8, do you mean there is a test account we can all use? Or should each of us try to create an account.

Are you using percentage sizes such that several children are adding up to use 100% of the outer container? It looks like we are sub-pixel snapping at 100% zoom and sometimes going one bigger than the viewport size, causing scrollbars.

The issue might be resizing things during hover animations too.

If this guess is right, does the problem go away if you modify the percentages to sum to 99%?

Regardless, this is a Layout issue, I think.
"If this guess is right, does the problem go away if you modify the percentages to sum to 99%?"

I have applied your suggestion, but it doens't work.

I have uploaded a new video, during hover animations the boxes/selectmenus doesn't change their size.

The problem is that the scrollbar, which is appering, is not scrollable. It cannot be a layout issue.

So not a sizing issue. I blame layout because that is what determines the need for a scrollbar. It's probably not scroll-able because the content is already almost fully visible.

Test account? Does it already exist or do we need to create one each?
