I have just started learning Unity 3d, and have run into an odd issue with pop-up windows:
On the game tab, if I select the resolution/aspect ratio drop down menu on the upper left and click “+”, the pop-up window appears for a fraction of a second and this disappears.
Something similar seems to happen if I try changing the background color for the main camera, but the color picker window only disappears if I try to move the window.
I run the appimage in the terminal, but it doesn’t seem to provide any useful data on the issue. Neither does JournalCTL. Any help would be greatly appreciated. I am running 2019.4.1f1, though I tried 2020.1.0b15 and that didn’t make a difference.
Here is a pastebin of my system data: Ubuntu Pastebin
