Bug ID: 505531
Summary: Brave (Chromium) fullscreen not covering screen
properly on Wayland + Nvidia until reentered
Classification: Plasma
Product: plasmashell
Version First master
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: tamim...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Description:
When using Brave browser (Chromium-based) on Fedora 42 with KDE Plasma (Wayland
session) and Nvidia proprietary drivers, entering fullscreen sometimes results
in an incomplete fullscreen display (e.g., visible bars, gaps, or offset).
This can be temporarily fixed by exiting and re-entering fullscreen mode
multiple times.
After investigation, a workaround was found:
1. Visit brave://flags/#ozone-platform-hint
2. Set “Preferred Ozone Platform” to “Wayland”
3. Relaunch the browser
This resolves the issue completely and consistently.
It's unclear whether this is strictly a KDE bug, but since the issue affects
window rendering and surface management on Wayland, I'm reporting it here so it
can be referenced or redirected appropriately.
Steps to Reproduce:
1. Open Brave browser
2. Play a YouTube video or similar content
3. Press F11 or trigger fullscreen
4. Observe the window not fully covering the screen
Expected Results:
Window should fully cover the screen when entering fullscreen.
Actual Results:
Window covers only part of the screen; sometimes gaps or bars are visible.
Workaround:
Use brave://flags/#ozone-platform-hint → Set to Wayland
Additional Info:
- KDE Plasma version: 6.3.5
- Kernel: 6.14.9-300.fc42.x86_64 (64-bit)
- PU: Nvidia RTX 2070 + proprietary driver [rpmfusion.org/Howto/NVIDIA]
- Brave version: v1.79.123 (Jun 11, 2025)
- Wayland session
