Public bug reported:
Environment
GNOME Shell 50.1, Wayland session
Mesa 26.0.8 (Ubuntu 26.0.8-1ubuntu0.3)
GPU: Intel Panther Lake [Arc B390], kernel driver xe
Hardware: Lenovo ThinkPad X1 Carbon Gen 14
Kernel: 7.0.0-34-generic
Distribution: Ubuntu 26.04.1 LTS
Steps to reproduce
Focus any window (e.g. Nautilus).
Press Alt+PrtSc, or open the screenshot UI (PrtSc) and select Window mode.
Actual result
Alt+PrtSc saves a PNG with the correct window dimensions, but the content is
blank (white/empty).
In the screenshot UI's Window mode, window outlines are drawn in the right
positions, but their content is empty.
Expected result
The window content is captured.
Additional information
Screen and area capture work correctly.
Window thumbnails in the Activities overview render correctly.
It happens with both fractional scaling (scale-monitor-framebuffer enabled) and
100% scale.
It affects both native GTK apps (Nautilus) and Electron apps.
Nothing is logged in the user journal when the capture fails.
