I upgraded to v0.1.9 last night. Did a quick test but didn't watch anything for more than a minute.
Today, the non-news channels using v.0.1.9 had a stuttering picture but not horrible. CNBC (lots of tickers, moving graphics, etc.) would play with increasing stuttering and eventually freeze, unable to recover. Non-news content did not have the issue of freezing, just nominal stuttering.
I removed v0.1.9 and reverted back to v0.1.8 and all channels, including CNBC look great.
Running on Win 11.
