This is about Embedded PDF in IE frames from a production application that is not shown correctly via Remote Desktop. When we connected via RDP to the office computer showing the PDF and my existing machine (from where the RDP session is opened) has a display scaling that is not equal to 100%. The Foxit PDF Editor/Foxit PDF Reader Interface is not shown correctly. With the display scaling set to 100%, it will work fine.
The following picture is showing the production application and the embedded PDF：
As you can see several panes are shown twice, others like the print button not entirely.
Cause and solution:
The DPI setting mode of the product application itself for rendering the embedded PDF files might be “Process_DPI_Unaware“, whereas the DPI mode of our Foxit PDF Editor/Foxit PDF Reader for rendering embedded PDF files is “Process_Per_Monitor_DPI_Aware” this mode. The two modes don’t match, the embedded PDF file is scaled 2 times with inconsistent data eventually, that is the reason why the Foxit PDF Editor/Foxit PDF Reader Interface is not shown correctly. You could choose to change high DIP setting for the Foxit PDF Editor/Foxit PDF Reader application to get around the issue. (Take setting for Foxit PDF Editor as an example)
If you are an individual user of Foxit PDF Editor, do the following:
1:Right-click the Foxit PDF Editor application icon from desktop or Start menu,and select "Properties" option in the pop-up context menu to bring up "Foxit PDF Editor Properties" window.
2:Click on the Compatibility tab,click on "Change high DIP settings"button to open a new window.
3:In the newly pop-up window,please check option "Override high DIP scaling behavior,Scaling performed by:" which is under the "High DIP Scaling override" section in this window .
4:Please select "Application" from the drop-down menu,click on "OK" "OK" to save the setting. Then please try to open the embedded PDF file from a product application to see if the Foxit PDF Editor UI will be displayed properly.
5:If scaling peformed by "Application" doesn't solve the problem,please repeat the above mentioned step1 to step3 ,and select "System (Enhanced)" this option from drop-down menu to see if it will help?
In general, set one of them ("Application" "System (Enhanced))" from the "Override high DIP scaling behavior, Scaling performed by: “drop-down menu could solve the problem.
