Garbage/Uninitialized content is displayed at startup before read display #374
Description
Hi,
When I run cargo run -p wgpu_texture --release, I found that there is a bug at the startup time of the example project
20260317_152805_1.mp4
from video time 00:00 to 00:03 (or stopwarth time 05:49.976 -> 05:50.319), the blitz windows is displayed but its content is displaying some garbage / or uninitialized content (the content is actually from my second monitor), and that display will continue for about 400ms. (from the stopwatch page's counter)
I think this is a bug, the expected behavior should be, the window is displayed, at the duration when wgpu is not ready, it should display white/black or theme color when set / or splash picture if implemented.
The bug is recorded on Ubuntu 24.04.
When I do the same test on Windows, the Window content is white during wpgu initialization.
