Hi! It took me a little bit to narrow down exactly what was going on, but I've got screenshots and video!
What's going wrong:
When I launch the game, the window is out of position, and missing the close button. When I maximize the window, the close button appears, but so does a black bar across the bottom of the screen. When I click or alt-tab to another window, the game adjusts and removes the black bar, but if I'm in-game while it happens, it breaks all the sliders and makes setting storage limits difficult.
Steps to Reproduce:
Launch game, observe that window is misplaced and missing controls.
Maximize game, observe weird black bar.
Click outside game or alt-tab to another window, game will adjust itself
Video Demonstrating Issue:
I've attached my Player.log and the log of the session that I recorded in the video, because it looks like a UI bug.
It's probably in the logs, but I'm running cachyos on the Linux 7.2.7-1-cachyos kernel, my graphics drivers are Mesa 26.2.3-arch3.1, and my proton version is the default on cachyos, proton-cachyos-slr 1:11.0.20260703-1. All are current and up-to-date as of the time of posting.
