Hello, my problem is exactly as the title states. Never used to happen, as I used to alt tab constantly since I have 1 monitor. I'm not sure what changed as I haven't touched my TF2 files in months and I barely play the game these days. I would say I first noticed this maybe about a month ago? It does not happen if I remove the -vulkan launch option. Disabling fullscreen optimizations doesn't seem to change anything.
If there's nothing that can be done I will just stop using -vulkan, but I do enjoy the performance increase I got from it. I use DX 100. Let me know what specs or additional info, if any, is necessary. Thank you!
