About once a day, at a random moment, there is a brief pop-up appearance on my screen of an UXTerm window, which then disappears after a split second.
Obviously, this happens due to some sort of rendering bug somewhere. All my UXTerm instances are started minimized with the
-iconic parameter. They are started roughly every minute, all day, and normally do minimize before ever being drawn.
But the problem is that for unknown reasons, it sometimes is drawn before being minimized. This is very annoying. I want to stop this if possible.
I’m somewhat sure that this only started happening when I recently switched from the open-source “MESA” GPU drivers to the closed-source NVIDIA drivers. The reason I switched is that the MESA drivers were painfully slow to the point of making using the computer basically impossible. So it’s not an option to switch back to MESA.
(But at least it doesn’t freeze my machine completely like the NVIDIA drivers did when I was using XFCE. That was really crippling. I can’t tell if this is KDE Plasma being better coded, or if they fixed this issue in an update between me switching DEs.)
Is there some way to avoid this annoying “flashing window”? And how is it possible that it happens only “occasionally”? Shouldn’t it either happen all the time or never?
At first, I thought that it only happened when I was viewing a video in fullscreen, but today, it even happened as I was browsing a normal webpage, so it seems like it can happen at any time.
Any clever workaround I could use to never have to see this?
Specs: KDE Plasma 5. X11. NVIDIA GPU drivers. All latest versions according to APT in Debian Linux.
Edit: After posting this thread, it happened several more times in a short time span. Bizarre.
