Hi frederic.boisdron ,
Could you please let us know if this is happening with specific file or with other files as well?
Also, try to perform following steps :
1 -Reset Acrobat Preferences ,close Acrobat XI,go to C:\Users\your username\AppData\Roaming\Adobe\Acrobat\11.0. ,move the entire 11.0 folder to some other location like temp folder .
To view temp folder , press Windows+ R key on your keyboard,type temp in the run dialogue box then press enter.
If App data folder is not visible under your user name , launch Windows Explorer then click Organize in the top left corner of the screen>then click Folder and search option>under View>Hidden files and folders,click Show hidden files, folders and drives>then click Apply and OK
Launch Acrobat again and check if its working fine.
2-If step 1 doesn't fix the issue , try to disable protected mode , launch Acrobat>click on Edit menu then click Security (Enhanced)>click Protected View>and then click Off>OK.
3 -If step 2 doesn't fix the issue,try to repair Acrobat>launch Acrobat>click on Help menu>then click Repair installation. After repairing , restart the computer and then launch Acrobat and check if its working fine.
Let us know if above given steps worked.
Many thanks Shivam,
Unfortunatelly, I already tested all this and it doesn’t work.
When adding text, the screen is still blinking each time I type on a key and the CPU consumed by Acrobat.exe *32 is still reaching 100% of one CPU Thread.
I have attached the PDF example for which problem is occurring.
Maybe you can try yourself with this PDF file ?
Thanks a lot for your support,
Thanks a lot Shivam,
I have sent the attachment to your private email as you proposed.
Thank you for sharing the files with us, we tried to reproduce the issue at our end, and the file you sent are complex in nature and due to the technical limitation, Acrobat is displaying that behavior.
