Are you using display resolution switching?
I've just noticed an issue with the display resolution changes I
pushed last week where it is creating/using display resolution
handling classes when it shouldn't be.
But I think your issues pre-date those commits??
I'll push a fix tomorrow.
Thanks for the perseverance:)
regards
Mark
