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. output: Using Mesa Intel(R) HD Graphics 520 (SKL GT2) (Gl) Avg frame time 15.864518ms Avg frame time 16.645708ms Avg frame time 16.64359ms Avg frame time 16.645853ms Avg frame time 16.645884ms Avg frame time 16.645628ms Avg frame time 16.643642ms

It works fine with changing the present_mode to Fifo.
