I've had WinSCP open for a few days, and it acts a bit strangely when I'm switching in and out of games. I suspect that this is a UI issue caused by this. I have a 4K screen on a 15 inch laptop, and a graphics driver that struggles at over 1080p in 3D games. My display settings (windows 10) are set to 250% for the main monitor. When I open a game (in this case XCom 2) it switches back to 100% as the game changes the fullscreen resolution from 3840x2160 to 1920x1080, and if WinSCP is open at this time the UI goes strange. Switch back and forth enough times while copying files and I see this crash.
I start the WinSCP and error message appears immediately.
I start the computer and winSCP firstly and get error message, but I restart my computer and winSCP firstly again and no error message. I do not understand. I reinstalled the app but it did not solve it.
