There is a known bug in the Chromium engine that affects all Electron apps, of which Obsidian is one. It causes blue and green distortions on all windows. This is due to a GPU rendering issue for some recent MacBook Pros.
Here is a screenshot
See https://bugs.chromium.org/p/chromium/issues/detail?id=1068170 for full details.
Steps to reproduce
- Change display modes, or wake the Mac from sleep.
- See distortions.
- Operating system: MacOS 15.7
- Obsidian version: 0.9.11
There are only two effective work-arounds:
Go to System Preferences > Energy Saver and restart the Mac. This prevents future occurrences but limits your ability to use the GPU for other applications.
Open up Activity Monitor, and view the CPU tab. Filter for the process 'Obsidian GPU" and repeatedly force quit the process or processes until the visual distortions disappear.
NOTE: This is not an Obsidian issue per se; however it might be helpful to offer a toggle for disabling GPU rendering until the issue is fixed.
