Description Andrew Sheldon 2019-10-21 06:58:21 UTC

I get X lockups with a Navi 5700 XT and HWCursor enabled. Only seems to happen if TearFree (and VSync) are disabled. I can reliably reproduce this with The Witcher Enhanced Edition with TearFree off (the game doesn't support VSync without forcing it), run with D9VK. These are recoverable at least (just need to restart X) and it doesn't cause a GPU hang, just frozen mouse.

If I run with TearFree on, a multi-monitor setup, or with SWCursor forced on, the issue goes away. I've also never seen the bug with a Vega card, although I can't say if it happens or not with the exact kernel I used. I'll also add I typically run with Freesync enabled, but it doesn't appear to affect things in either direction.

The issue also happens seemingly randomly with other games (like Kingdom Come: Deliverance and the native Steam client).

Reproduction steps:
1. Run "The Witcher: Enhanced Edition" with D9VK with TearFree off and HWCursor enabled, in a single monitor configuration
2. Move the mouse around during the main menu
3. X lockups with the following message:
