Window stops updating after screensaver

Any Xojo gurus got an idea how I might track this one down?

Here’s what a normal window looks like

And here’s what it looks like after the screensaver deactivates:

The app still works but the window is mostly frozen. Some containers will show on demand but the window itself won’t update even if resized, maximised, hidden, etc. Sometimes during extreme resizing a bit of the missing UI can be dragged on screen as if it located off left of the screen. However controls that are still visible are unresponsive.

Menus work and modal dialogs, preferences screens, etc display fine.

This happens infrequently enough to make debugging almost impossible but often enough that customers complain.

It’s a complicated app with timers and self updating views but this affects every element, even static elements.

As far as I can tell, this problem started in Xojo 2025 r2.

Problem doesn’t exist on Mac version of app.

I’ve noticed this exact same thing on a single pc running Windows 10. Same software runs on tens of machines (w10 & 11), happens on just one.

Xojo Issues #70271

Without any comment on why such a bug exists even though reported in 2022.

Thanks for the issue link. I added my support for it.

I see the bug has been fixed for Xojo 2026r1 :slight_smile:

I’ve seen that with apps not made with Xojo.
I wonder if this is a Windows bugs.

Well asked if it was fixed just for the IDE or for apps built with Xojo. Hope it’s fixed also for apps except if it’s a Windows bugs like Christian said

Yes, assuming and hoping it fixes it for built apps too.
