Bug Description
UI components are glitchy, rapidly appearing and disappearing. Same as #1879 except its not the whole screen.
It's kinda similar to those Wayland bugs in the early days.
It's way worse than what it looks like in the vid:
output_video.mp4
Steps to reproduce the behavior
- Just open the app on Kubuntu 25.04
Expected behavior
No flashing
Ubuntu release
Other (specify in the last field)

Additional context
I am using Kubuntu 25.04 with NVIDIA
I suppose this is related to this upstream bug
This is a hardware acceleration issue.
The same thing happened to me when I used Vivaldi, for example. But using software acceleration solved my problem.
On modern machines or those with dedicated graphics cards, this issue doesn't occur. However, on older machines, this error occurs in both the Installer and the App Center, which are built in Flutter.
Having this exact same issue on the App Center. Freshly installed Ubuntu 25.10 GNOME running an AMD cpu and NVIDIA RTX gpu. Same as @xgrind mentions, noticed this earlier in the Installer as well.
Having this exact same issue on the App Center with 24.04/25.10. Both I+N and UMA can reproduce the issue.
When opening the App center, the application page will flash for about one second, especially scrolling, and when entering letters in the search box, the option box will flash for a few seconds.
It sounds the snap-store load the icons from server, and then reflash the windows each time. Clicking 'About', it's easier to reproduce this issue too.
