Having this bug too. Don't know what launcher version because it fails to launch, but I just installed it from the installer. System is Windows 10 x64.
When the bug occurred, I was connected to a VPN. (I'm physically in China Mainland, and the VPN server is in Hong Kong. The VPN is provided by my college, but there has been no report from my college's students or staff members that the VPN has restricted access to websites.) With the VPN, the bug occurred. I tried disconnecting from the VPN, and the bug no longer occurs and shows an update dialog with a download bar, but thanks to me being in China, the download does not make any progress whatsoever :-/
I can confirm this: it happens to me.
I'm helping building a server and when testing locally (PC, international windows 10 version, exact minecraft version unknown but it's after the update where /kill can kill creative mode players), /spreadplayers (with range 9999) was done within a few seconds but since then the game lags hard (roughly one game tick per second, behaves as if server is running slow but client is running at full speed), and it could only recover when exiting and re-entering the world.
Then I went to the server (server spec unavailable; it's on NetEase's server. Running a Chinese Minecraft version that is after all Aquatic updates but before /kill kills creative mode players.), with range 50000 the server froze for a few solid minutes before being able to return to normal.
Works as intended?? Maybe they just added that purposefully.
Suggestion: WORKS AS INTENDED
When there is a non-transparent block or a mob in the direction the lid is opening into, it will not open. It's totally normal.
Same, Bedrock 1.2.5 China Edition on Android. Attempting to place the "block" will actually place nothing while decrementing the item count in the inventory. The info update texture also sometimes appear when mining such moving blocks as a particle effect produced by mining/breaking, even when the movingBlock item is not the one that actually drops.
Same problem on v1.2.5 China. Note that for this bug to happen, you should be on creative mode or point to a instant-destroy block (eg a crop).
Same problem with signs, book and quills and inventory search, v1.1.5, v1.1.? China, v1.2.5 China, Huawei P10 on Android 7. On 1.2.5 China it even hides everything and shows the background of the Main Menu (of Minecraft, not of the launcher) w/o any GUI.
Same problem, with signs (happens on v1.1.5, v1.1.? China, v1.2.5 China), book and quill (only page editing mode, not title/author editing mode, happens on v1.2.5 China) and 1.2 inventory search (pocket UI, didn't test classic UI, happens on v1.2.5 China). Device is Phone - Android - Huawei P10 (Android 7). I might add some screenshot or screen recording later...
Personally I call that Works as Intended (it's only natural that lzh, which begin with l, doesn't sort with zh-XX, which begin with z). But yeah I get the point that it also makes sense to have classical Chinese sort with other Chinese variants.
