**Description**
When using an Overlay navigation target in Glide, navigating on iOS into a sub-page and then going back causes a visual glitch. Specifically, when returning to the previous screen, the intermediate page briefly flashes over the destination screen during the back animation. This creates a noticeable flicker and breaks the expected smooth transition behavior.
This issue is also visible in the Glide Editor preview. It does **not** occur on desktop, likely because there is no animated transition there, which suggests the issue is tied to the mobile animation itself.
Overlay navigation is important here because it preserves the user’s position on the previous screen when navigating back (both on mobile and desktop). This makes it significantly more usable for list-based UIs. By contrast, using “Current” navigation resets the user’s position when returning to the previous screen, including on desktop. If “Current” preserved scroll position consistently across platforms, it would be a viable alternative to Overlay in this case.
**How to replicate**
1. On iOS (didn’t test Android), open the app: [https://animationbug.glide.page](https://animationbug.glide.page)
2. On the first screen, tap any contact in the collection (this action is set to “Show detail screen for this item” with Target = Overlay).
3. You will be taken to a detail screen presented as an Overlay.
4. From this overlay screen, tap the first or only company listed (this can be any action; Target can be either “Current” or “Overlay”).
5. On the sub-page, tap the back button to return to the previous screen.
**Result:**
During the back navigation, the currently-viewed (sub-) page briefly flashes over the main page/screen you are returning to, creating a visual glitch.
**Expected behavior:**
The transition back should be smooth, with no flashing or intermediate screen artifacts.
**Notes:**
- The issue only requires the initial navigation to use Target = Overlay.
- The sub-page navigation does not need to use Overlay; it can be set to Current and the issue still occurs.
- This appears to be specifically related to sub-page navigation within an Overlay context.
- Reproduced in a default app with 1 configuration change - main collection action gets “Overlay” as its Target instead of “Current”.
- Since the issue appears tied to the mobile animation (and does not occur on desktop), a potential fallback would be to disable or simplify the animation on mobile if it cannot be resolved cleanly.
- Let me know if you need any other info. I would absolutely love to see this fixed.

Just a quick follow-up - not trying to rush anything, just hoping someone can confirm this has been seen.
I wouldn’t normally seem so impatient but I only get one published app on my plan and I’m using that slot for this repro. Once someone from the team confirms they’ve reproduced it or grabbed what they need, I can free it up.
For any Glide Experts who come across this, is there a good way to make sure this reaches the dev team? Or if you have an available slot to publish an app somewhere, can you replicate the page and I can update my link to use yours?
To recap how minimal this repro is:
- Default app, zero data changes
- Only one configuration change: main collection action set to **Target = Overlay** instead of “Current”

Thanks in advance 🙏

You can submit a ticket through the bottom right icon in your builder.
I can see the problem on iOS.

Thanks @ThinhDinh, I think I was able to do that last night.
