I can't run any example from source.
system:EndeavourOS(base on arch)
kde plasma version: 5.26.4

cpu:i3-6006u
gpu:intel hd 520

It's not KDE, it's WGPU on older Intel graphics hardware. Please try wgpu examples and see what works.

You can also try changing the present_mode to Fifo in crates/kas-wgpu/src/window.rs:141. No other change required.

It has the same problem on another computer that only has a different processor(CPU:AMD R5-5600H).

I tried some wgpu examples like https://github.com/gfx-rs/wgpu/tree/master/wgpu/examples/water, it works fine.

It works fine with changing the present_mode to Fifo.
