Steam Client Beta - September 30, 2019
30 SEP @ 11:43PM - JMCCASKEY
The Steam Client Beta has been updated with the following changes:
Note: This update includes a number of fixes for making sure users can keep GPU web view acceleration on without negatively impacting GPU usage when Steam is not in use or a game is running. GPU web view acceleration is important for good new library and friends ui performance. If you have previously disabled GPU acceleration this update would be a good time to try it again.
General:
- Improvements to prevent new library doing any animation/GPU work when the library window is covered by other windows or games regardless of GPU acceleration settings
- Some library animations now pause when the library window does not have keyboard focus or mouse hover, even if the window may be visible
- Fixed a steamwebhelper memory leak impacting Mac and Linux users and some Windows overlay browser usage if GPU acceleration for web views was on
- Fixed web view GPU acceleration to default on for Mac and Linux
- Fixed library failing to load for some users with very large numbers of non-Steam games
Linux:
- Steam Linux Runtime updated (0.20190927.0):
- Disable obsolete SSLv3 in libcurl, fixing a libcurl problem on Arch
- Disable LDAP in libcurl
- Update SDL2
