Comment 32 for bug 1911036

RE: https://gitlab.xfce.org/xfce/thunar/-/issues/532

Not wanting to run an unsupported configuration and hoping for a workaround, I tried the suggestion in that issue and disabled display compositing in Window Manager Tweaks. While it did indeed seem to "fix" the drag issue in all the affected apps I mentioned, it had the unfortunate side effect of terrible graphic artifacts and weirdness happening all over the place, mostly in my terminals. It was too unusable to continue with it disabled. As soon as I re-enabled it, the graphical artifact issues stopped and the drag issue resumed.

FWIW, disabling display compositing in Window Manager Tweaks does indeed freeze the current X session as mentioned but enabling it does not.
