Bug on Scrolling
FizboIV opened this issue · comments
Hi,
I'm working on a simple machine interface using
- RaspberryPi 4b
- Raspberry 7" touch display 800x480
- OS: RaspberryPi OS Lite v 11 Bullseye
- Weston v.9.0.0
I implemented a scrollable table and every time I scroll everything except the table vanishes.
How it looks like before scrolling:
How it looks like after scrolling:
I also build the flutter app for web. There's everything working fine and as expected.
Do you have any ideas how to fix it?
Thank you
Can you check if this issue occurs on flutter for Linux desktop or Android/iOS? I believe this doesn't depend on flutter-elinux. I think it depends on flutter-engine or flutter framework. Also, please check your Dart code, too.
Just FYI.
I also build the flutter app for web
flutter engine of the flutter for web is completely different from desktops and mobiles (iOS/Android). Thus, flutter for web is not helpful.
I tested a bit today and it does work on iOS. I checked on iPhone and iPad. Unfortunately I can't test on other platforms.
I also noticed that as long as I plug in a mouse and scroll with the mouse the bug doesn't not happen. Maybe it is a problem with the touch input?
Can you share the source code?
code can be found here:

its the custom_table widget that is malfunctioning
Now, I could reproduce this issue.
@FizboIV
This issue occurs on RPI4 + Weston v9, but it doesn't happen on RPI4 + Sway. Can you please try to run the app using Sway instead? IIRC, Weston is basically a reference design for Wayland compositor. I think it has some issues.
That did the trick! Thank you very much! I really appreciate it. :)
