Steps to reproduce:
- Open a Unity project
- Install URP (optional step but makes the issue much more prominent)
- Switch to Vulkan renderer by navigating to Edit > Project Settings > Player then deselecting 'Auto Graphics API for Linux' and dragging Vulkan to the top of the list
- When prompted, restart the editor. Wait for it to restart
- Resize and/or move around both docked and floating windows
Actual results: The Editor (and the window resizing) heavily lags, has visual glitches, and the console is spammed by memory warnings (can easily reach hundreds or even thousands of these spammed). The error reads 'Vulkan - Suboptimal memory type used for buffer because of low memory'
Expected results: The window resizing/moving does not cause heavy lag, visual glitches, and the console is not spammed by warnings.
Reproducible with versions: 6000.0.21f1, 2022.3.47f1
Not reproducible with versions: -
Can’t test with versions: 2021.3.44f1 (Editor will not launch, unsupported)
Tested on (OS): Ubuntu 24.04
System specs: Intel(R) Xeon(R) W-2295 CPU @ 3.00GHz. NVIDIA GeForce RTX 3070. 64GB Ram
Notes:
- While this is reproducible without a Render Pipeline installed. Having a Render Pipeline installed (even if not active) will cause it to happen on every window, even with small resizes. Without a render pipeline installed, it appears to mostly happen when a window is made really small or really large, but not at medium sizes.
- This issue is even more of a pain point because there is also a big issue with using OpenGL Renderer ([Internal link]), so switching to OpenGL rendering is not a viable workaround.
