This is getting annoying…
I havnt managed to work out whats triggering this yet but its happening alot, usually within 10-20 minutes of starting the editor.
I think but I’m not 100% sure this started after I got a new monitor, used to have a really old dell 24 inch 1920x1200 59mhz monitor. Now I’ve upgraded to a asus rog swift pg279q running 1440p 144mhz gysnc. I havnt really used UE4 for a few months before I got this monitor so could just be coincidence.
Basically after a short amount of time right clicking on anything that brings up a pop up menu doesnt work anymore, the pop up menu either flickers or pops up then disapears instantly. Also once this starts occuring opening up a blueprint just produces a black screen, alt tabbing out the editor and back in normally then shows the blueprint correctly.
Restarting the editor fixes the problem but then it’ll start happening again 10 minutes later.
Also the editor seems to break my monitor sometimes, i get a line that starts at the top in the middle and runs halfway down the screen. Looks a bit like the top right hand side of the screen has moved a few pixels over the left and now is not lined up with the rest of the screen. Now I think about it…looks kinda like tearing when you’re not running any syncing like vsync or gysync, but permanent. Restarting the monitor doesnt fix that issue but changing the mhz to 165 then back to 144 fixes it. No other software\game does this to the monitor.
Now I think about it…I’ll try running the editor with gsync switched off see if that makes any difference…
(EDIT: probably not gsync its set to only run in fullscreen mode)
