Diablo Immortal Patch 4.3 brought a lot of new headline features, from The Taking story content to PvP updates, new Legendary Gems, and quality-of-life changes. But while most of the official coverage has focused on what was added, some players are already talking about something less exciting: the PC client itself.
Over the last day, fresh Diablo Immortal forum posts have pointed to a small but notable cluster of post-patch PC problems, including keyboard controls failing to initialize properly, multiple in-game issues after the March 18 release, and even reports of the PC client trying to re-patch itself with a very large second download. None of that automatically proves a single widespread PC meltdown, but it does suggest that Patch 4.3’s rollout has not been completely smooth for everyone on desktop.
The cleanest new complaint is a keyboard controls bug
One of the clearest current reports comes from a March 20 Diablo Immortal bug thread titled “Keyboard bindings not initializing.” In that post, a player says that after the recent patch, their keyboard controls are not being initialized when the game starts. According to the report, opening the in-game settings and visiting the controller tab temporarily fixes it, which makes the issue sound less like a permanent total failure and more like a broken startup state on PC.
That may sound minor compared with a crash or a hard disconnect, but control initialization bugs are the kind of issue that instantly make a PC client feel shaky. If players have to poke around menus just to get their basic inputs working properly, the patch starts to feel a lot less polished than the feature list suggests. This is an inference based on the type of bug being reported.
Another player says the March 18 patch brought multiple in-game PC issues
The keyboard report is not standing alone.
A separate forum thread posted after the March 18 patch release is titled “Multiple InGame issues - PC Client - Post March 18 Patch Release (Americas).” The available forum snippet shows the player saying the problems persisted even after both a Battle.net Scan & Repair and a game load screen repair, which suggests they had already tried the most obvious first-line fixes before posting.
The snippet does not expose every listed problem in full, so it would be overstating things to claim Blizzard players are all seeing the exact same symptoms. But the thread is still useful because it shows that at least some PC users are treating the post-patch problems as more than a one-off local setup issue. They are specifically tying them to the March 18 patch window and to the PC client.
There is also a strange re-patching complaint
One of the more awkward reports involves patching itself.
In another recent Diablo Immortal PC forum thread, a player says the client downloaded the initial update, then later attempted to apply another much larger patch after they exited the game. The post describes a second update ballooning into a 15.19 GB re-patch after the first installation. That is just one report, so it should not be treated as a confirmed universal launcher issue, but it is the kind of thing that tends to get player attention quickly because it feels so obviously wrong when it happens.
If a content update is supposed to get players into the game faster, a surprise giant second download is pretty much the opposite experience.
The forum activity suggests this is part of a broader PC-side rough patch
The strongest reason this story feels worth covering is not one thread by itself. It is the pattern.
The Diablo Immortal PC and bug-report forum listings from March 20–21 show a cluster of fresh PC-related topics, including the keyboard bindings thread, the multi-issue post-patch thread, the re-patching thread, tooltip behavior issues, and a shop problem thread. That does not prove one shared root cause, but it does show that desktop users are actively surfacing a number of current problems in the same immediate post-patch window.
That makes this a better story than a plain “one angry player had a bad time” post. The available evidence supports a more cautious conclusion: some Diablo Immortal PC players are running into fresh issues after Patch 4.3, and those complaints are visible across multiple current forum topics.
This is not the same as saying Patch 4.3 is broken
That distinction matters.
Officially, Patch 4.3 is still a major content update centered on The Taking, the Rocky Waste zone, PvP revisions like Siege of Corvus and Challenge of Equals, new Legendary Gems, and other system changes. Blizzard’s own announcement is focused on those features, not on a public warning that the PC client is unstable.
So the careful read here is that the content update itself is real and live, while some players are also reporting fresh desktop-client problems around the same release. That is a more accurate framing than jumping straight to “Patch 4.3 broke the PC version.” The forum evidence supports the existence of current complaints, but not a confirmed Blizzard statement that the PC client is broadly compromised.
Why this overlooked angle matters
This is exactly the kind of post-patch story that often gets missed because it is less glamorous than new content and less explosive than a major monetization debate.
But for players on PC, these issues can matter more in the short term than whatever new activity or event just went live. New quests and PvP updates are great. They matter a lot less when your controls are not loading correctly or your client is acting like it wants another double-digit gigabyte snack before you can play. That last part is an inference based on the player reports and the kind of friction they describe.
If Blizzard responds quickly, this may end up being a brief rollout stumble that fades by next week. If not, it could become one of those quiet PC-client frustration stories that does not dominate the patch headlines but absolutely shapes how the patch feels for the people actually trying to log in and play it.
