OpenMW 0.52.0 RC1

This is the first round of release candidate (RC) builds of the upcoming 0.52.0 stable release, available for wider testing. Preliminary changes vs. the 0.51.0 stable release are listed below; further changes may occur in subsequent RC rounds and in the full release.

Flatpak (Linux)

Read the announcement blog post here.

Note that the saved game format has changed. Existing saves will be compatible with 0.52.0, but you cannot go back to an earlier release to load a save created in 0.52.0.

Known Issues

• On macOS, launching OpenMW from OpenMW-CS requires OpenMW.app and OpenMW-CS.app to be siblings.
• [#7511] On Windows, a freeze may be reported if engine startup takes too long; ignoring the message is usually harmless, as it should eventually disappear, but if it doesn't, please share the freeze dump with us
• [#8233] Hardware antialiasing may cause driver timeouts on AMD GPUs of the RX 6000 and 7000 series; this is a driver bug AMD has yet to address
• [#8255] On Intel GPUs, the game may freeze visually while still responding to input. This is a driver bug; as a workaround, you may need to install an older version of the driver
• [#9461] With newer AMD drivers, the explored map may look broken due to a zero division in the fog shader not being handled gracefully. Enabling exponential fog can act as a workaround
• [QTBUG-150017] macOS: Qt tools don't use the native design because of a style change workaround applied to avoid this yet-to-be-patched Qt issue

Fixes
