Description
Wayfire version
0.11.0-31beef5 (Feb 21 2026) branch main wlroots-0.19.2
GPU / Driver
deviceType = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU
deviceName = AMD Radeon RX 9060 XT (RADV GFX1200)
driverID = DRIVER_ID_MESA_RADV
driverName = radv
driverInfo = Mesa 26.1.0-devel (git-f71a38e9de)
Describe the bug
Pixel movement can feel jumpy, often tied to the game's region. This stutter is most noticeable during movement. In Gles2, the bug is worse. With the Vulkan renderer, it's more noticeable when starting wf-recorder, but even without it, the bug is sometimes apparent.
To Reproduce
Playing games is the only way for now

Research direction
No source file, test, or entry point is identified. Start by reproducing the stutter during gameplay and compare GLES2 with Vulkan, including behavior when wf-recorder starts. Done means isolating the rendering condition that causes the jumpy pixel movement and confirming the behavior is corrected without regressing the other renderer.
