Crash when playing games in 'fullscreen exclusive' on multi monitor setups

[doomx85]

At least these 2 games crash when having more than 1 monitor after about 15-20minutes of gameplay. If only 1 monitor is present the games work. Tested this at home and at a local LAN when trying to mirror to a projector. A local streamer also confirmed BO1 crashes while using 2 monitors. Hope someone can reproduce this. If any additional info is required please lemme know.

Software information

Confirmed for CoD:WaW and CoD:BO1 for now even with "dxvk.enableGraphicsPipelineLibrary = False" which is the only way to run WaW at all on without crashes.

System information

• GPU: RX 6800/ 6700XT/ 5700XT
• Driver: older and latest 25.9.1
• DXVK version: older and latest 2.7.1

Log files

Log files show no errors or warnings.

Hi there. Give latest master a try. You can download a build here https://github.com/doitsujin/dxvk/actions/runs/18729779581
Also please attach logs. Even if they don't contain any errors.

This just smells like you're running out of address space in 32-bit games.

2.7.1 (and possibly a few older versions too) indeed comes with a pointer invalidation bug related to multi-monitor setups (well, >1 adapter really), but it's fixed on master, see 10aacfd .
