image problem on Windows 64 & 32

Hello,

I just deliver my app with Xojo 2018R3 to my clients and I have a problem on Windows for 2 of them (over 700 for now).
They have the same problem. The background and buttons images are not displayed. And some object like the list are not clickable.
Here is what they see and what it should see.

Sorry I can’t help you with ideas/solution.

They may need to apply all relevant updates for Windows 7 - including any updates for Direct2D.

Hello,

You’re talking about directx update ?

My clients done this without solution for now.

Nobody has experiment this problem ?

I’ve seen something like this in the past when i had an exception in my code which i was not handling correctly. I think the Framework just stopped to draw the rest of the Containers when the exception ocurred.

I have found the solution.
It’s about the theme of Windows. I ask my client to choose a classic theme not an Aero one and now it’s work.

Thanks all
