On Nvidia 535, tearing/flickering observed with PresentMode::Fifo #5491
Open
Description
Description
I am observing tearing between 2 frames on Linux with X11 and Nvidia 535 drivers.
Repro steps
I have modified the "shadow" example in order to accentuate this effect: acarl005#1
This branch just renders 2 frames in rapid succession every 1 second.
Expected vs observed behavior
I observe the expected behavior on the integrated GPU.
WAYLAND_DISPLAY="" cargo run --bin wgpu-examples -- shadowPXL_20240404_024350904.TS.mp4
However, when I switch to my Nvidia GPU, I instead see tearing and/or flickering.
WAYLAND_DISPLAY="" WGPU_POWER_PREF=high cargo run --bin wgpu-examples -- shadowPXL_20240403_202650141.TS.mp4
The examples use PresentMode::Fifo, which says:
"No tearing will be observed."
Platform
Forked the current trunk branch of wgpu, commit ed843f802974eae9d708d3b3895264e9efb01dc6.
