Graphics instability on screensaver unlock

[lychee]

Hello,

Since installing Manjaro, I’ve had an issue which occurs when I unlock my computer. Some apps, for example Discord, will stop rendering new images (but still process mouse movements, as the application titlebar still changes). Most games crash, and Steam seems to get some texture mapping issues. But, again, this only happens after I’ve locked my computer. Everything works fine after closing & reopening it. I’ve tried switching from the proprietary driver to the opensource one, I’ve tried disconnecting one of my two monitors, I’ve tried using integrated graphics, all to no avail.

I’m not well-versed in GNU/Linux, so I don’t really know what else to do to troubleshoot, any help you can provide is much appreciated

The issue has occurred since I installed Manjaro about a year ago, so installing it would be the only prior action.

I think the issue is something to do with GPU memory access permissions changing when the system locks, but I don’t know anything about drivers & the like, so I don’t know what to do with that info
