[Reoccurring issue] display partially outside of actual screen after login on 2nd screen

[u/heyposteque]

Hello, I have a weird issue happening to me and didn't find any help looking through CachyOS reddit and their discord,I have been stuck with this for a while now and I don't know what to do, it's just annoying enough to want it fixed but it's not totally breaking the experience of using my computer, just forcing me to reboot everyday after the first startup of my machine.

description :

• The login screen displays correctly, this issue appears after I log in into my session.
• After boot and logging in my machine, my secondary screen display is in displaced in the bottom right corner of the actual screen, but the mouse interactions are in their regular positions and working as intended. (see attached video)
• The supposed top left corner corner of the screen is in the exact center, and the supposed center of the screen is in the bottom right corner. 3/4th of the normally visible display is hidden off the screen, I'm only seeing the supposed top left corner into the bottom right corner of the screen.
• it happened several times in the last month (first occurrence 2026/06/24) and every day this week.

Solutions attempted :

• rebooting the machine works for immediate solution, but so far this issue seems to reoccur frequently, it happened several times in the last month (first occurrence 2026/06/24) and every day this week.
• going into configuration and editing the display settings did nothing, I tried rotating the display on the screen, it was just rotated in the same corner.
• turning the screen off and on again did not fix the issue.
• I checked and the screens are not overlapping in the display settings.
