Please describe your issue in as much detail as possible:

From a few updates (especially the battle pass update) during the game I started to observe huge graphical problems emerging in Dota 2 using Vulkan on Linux.

Here is example:

Dota 2 Vulkan API OS: OpenMandriva Cooker Mesa 21.1.3 GPU: Radeon RX 580 8GB LLVM 12.0.1 DRM 3.40.0 Kernel 5.12.8

Worth to add that with the battle pass update, the game performance on my computer dropped drastically (with unchanged graphics settings). Should I report the performance issue in a separate report?

For what I tested only the Vulkan API. I did not check the OpenGL case yet.

This usually happens after playing a few games. Was this in the first game you played?

[AngryPenguinPL]

I honestly don't know. I never thought about when these problems occurred, whether on the first game or on the next. I'll check next time.

Sometime it happend in first game but in most of cases it its with second, third or another game.

Also this issue is only on Vulkan. OpenGL works fine even performance is now better with OGL than with Vulkan.

I have vulkan memory leak, when dota eat all my ram, my pc crash, only hard reset.

I have a similar problem. After 3-4 games, Dota becomes very slow and the graphics can become low poly. Basically everyone is a yellowish blob

I'm on an RX 580 as well and have this issue.

I'm also experiencing the memory leak issue with Vulkan. No problem with OpenGL. Here's my specs gist.
