Can I change the blue background color shown when I select a file or folder?

That should be the correct GUID for Adobe: {DC6EFB56-9CFA-464D-8880-44885D7DC193}

Does not seem to work here. It actually kills my IDE (something which happens VERY rarely). Typical Adobe behavior.

... Typical Adobe behavior.

Typical XY behaviour!

I've been using Adobe for nearly 30 years, it was first published on June 15, 1993. I HAVE NEVER HAD ANY PROBLEMS, I used it for almost twenty years creating documentation for work.

According to the web, dated 14 June 2018 "In the past year alone, some 200 billion PDFs were opened in Adobe products."

Obviously, they didn't use XY.

Sorry for the late response.

I have some questions to you:
1) Do you see the problem also at 150%?

yes

2) What is your Windows version?

win10 20h2 19042.1415

3) Does your PDF preview show multiple pages of a PDF, or just an image of the first page?

It Show multiple pages and I can scroll through many pages.

Untick Configuration | Other | Shell Integration | 64-bit Windows | Use 64-bit preview handlers for preview
-> The problem will be solved. It works well 200%

Thanks. From v22.60.0103 onwards it should be solved for any scaling and any setting of "Use 64-bit preview handlers for preview".

I had a similar issue with a dual monitor setup that affected most programs. My setup is a laptop with a 16:10 2560x1600 screen and 2nd monitor at 16:9 2560x1440. Setting the laptop at 150% scaling (so I could see what I'm working on) @2560x1600 and the 2nd monitor at 100% @2560x1440 would cause issues if I tried moving a window from one screen to the other, or if a window opened in the 2nd monitor but was previously closed on the other monitor. From my reading, Windows 10 does not do well with multiple monitors at different monitor scaling. A test is to move a window that correctly displays on one screen and move it so 1/2 of the window is displaying on each monitor. On my setup, as the window is moving across both screens you can see where Windows is adjusting the scaling first but not the resolution or aspect ratio. Sometimes it works, but more often it does not and weird things happen watching Windows trying to adjust scaling/resolution from one screen to the other. My laptop screen uses the laptop Intel Graphics and the external monitor uses the laptop board Nvidia graphics card so that may have something to do with the scaling issues I experienced.

Windows 11 supposedly works better with dual monitors at different scaling. My fix (Windows 10) was to keep the 2nd monitor at 100% scaling (at 2560x1440 resolution) and select a laptop screen resolution that works for me at 100% scaling, in my case 1920x1200 which maintains the screen aspect ratio of 16:10.

Right, I'm using 4096 x 2160 uhd monitor
HIDPI is 200%.

I changed it to 100% after listening to you, so it comes out well.
I guess my HIDPI was the problem.
But 100% HIDPI is too small to keep using.

I hope this problem will be solved one day.
