Probably there is an error in the size (width or height) of the iFrame (not in the size that can be specified by parameter) as soon as you change the positions (X or Y) by parameter.
Short explanation:
On one page 2 iFrames are used, which change position in the interval of e.g. 30 seconds. The width of the visible area is 1366 pixels. The iFrame, which is outside the visible area, should load the same page after 15 seconds by adjusting the SRC parameter to read new values. The page load should not be visible. Once the page has been loaded and the 30 seconds have elapsed, the two iFrames swap positions. After the iFrames have exchanged their positions with each other, everything still looks good. However, if the SRC parameter of the invisible iFrame is now adjusted, the display of the visible area changes, with the content having completely incorrect positioning.
X-Position of first frame: iframeX1 0 Pixel -> 1366 Pixel
X-Position of second frame: iframeX2 1366 Pixel -> 0 Pixel
Changes after 45 seconds:
Src of first frame: targetURL 1 -> https://Excelpage.com?timestamp=15-00-45
From here on, the second iFrame behaves strangely. As if at this point the SRC parameter of the second iFrame is also adjusted, although this is nowhere the case.
I hope that the error description helps to some extent :)
