Just wanted to chime in and join the ranks of "i have this bug"
And i have had i for a long time. Switching from 5120x1440 to 2560x1440 didn't help.
so, for me atleast, it is not resolution based.
Tried the "legacy scaling" fix suggested earlier. Didn't fix it.
Would be nice if DE could specify the type of info they need, or maybe reach out to some of us having the bug, so we can assist in reproducing it or share specs/data...
