It's generally functional and works well. Does not solve the problem described in BZ#1458845 though (I cannot resize the test document beyond 97.4%).
Initial manual testing indicated that it's working exactly as it should - package upgraded fine, bugs fixed in 0.74.3 upstream are indeed fixed and performance seems close to the DOSBox compiled manually.
More testing will follow in a few hours.
Thank you! :)
@lemonzest - what hardware / drivers did you test with? Was it in a VM or real hardware?
Personally I tested with AMD and Mesa drivers - for me it works fine with OpenGL, but I would prefer to know what's causing the OpenGL-related crash.
