Linux: High CPU load on screen unlock, .xsession-errors fills disk

Since updating to Obsidian v1.0…

After waking up from locked screen (xfce4 + light-locker), with Obsidian running, three or four cores are pegged at 100% for about 25 seconds. During this time Obsidian window is unresponsive. At the end of ~25 seconds Obsidian becomes usable and CPUs return to normal.

During the ~25 seconds, the following error:] renderergl_utils.cpp:188 (ClearErrors): Preexisting GL error 0x00000507 as of …/…/third_party/angle/src/libANGLE/renderer/gl/TextureGL.cpp, setStorage:1036.

…is being logged to ~/.xsession-errors at the rate of 25,000-30,000 times per second.

I tried this with the Obsidian Sandbox and the same thing happened.

Steps to reproduce

  • Open Obsidian Sandbox
  • Lock screen
  • Wait until login/unlock screen reappears
  • Unlock screen
  • watch CPU graphs and line count in ~/.xsession-errors :slight_smile:

Expected result

Should be able to use Obsidian right after unlocking screen. CPUs should not catch fire. Disk should not fill with errors.

Actual result

This doesn’t happen to me on linux. It may be something specific to your system or desktop environment, or maybe a problem with a newer electron version. These things are beyond our control.
You can try to disable hardware acceleration in obsidian (settings>about)

Thank you. That seems to have fixed it.

I guess I will find out whether the note on the setting “If you turn this off, app performance will be severely degraded” is much of a problem." :slight_smile:

Thanks again.
