[Ubuntu] [Vulkan] Lag and console warnings when resizing/moving Editor Windows
*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 stuttering, and the console is spammed by memory warnings (can easily reach hundreds or even thousands of these spammed)

*Expected results:* The window resizing/moving does not cause heavy lag, visual stuttering, 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 ([https://jira.unity3d.com/browse/UUM-44222]), so switching to OpenGL rendering is not a viable workaround.
