Can not reproduce on 2.93.0 LTS. I would suggest to try with factory default settings (File -> Defaults -> Load Factory Settings)

I can reproduce in 2.93, make sure to have the translation setting set to simplified Chinese, and make sure to check the interface check box, before pressing f12 three or four time, and there goes three or four new render windows. Again, this only happens when you turn blender into Chinese interface @PratikPB2123

@Eary , Thanks. Can confirm now for 2.93.0 LTS. I guess problem is somewhat similar to #88755 (Blender opens a new render window even when one is open already.) and #88924 (Blender crashed while importing the file) (In both reports new instance of window created which was not reproducible in 2.92.0.

With fix for any of the task will probably fix the all the reports (Not sure though).

Pratik Borhade changed title from ~~The image editor will open unlimitedly in Simplified Chinese and some languages,When press F12 to render.~~ to More than one Render Window instances will be created after hitting F12 multiple times

Does this continue to happen if you change to Chinese and leave it that way? As in close blender and re-open? Does it always do this when set to Chinese? Or is it only when changing language until it is restarted?

It used to be that temporary windows could steal each others' spaces. So you could have a render window open, then select Edit / Preferences and have Preferences take over the render window. That was changed to fix that but it does rely on the title of the window. So new request to open a temporary window (like render or preferences) will reuse an existing window only if the titles match.

Hi @Harley , what I did is: Set language to any (other than default) then hit F12 multiple times (Multiple instances of render window were created)

Even if I restart blender after changing the language, problem is reproducible.

(Same problem is not replicable for 2.92.0)

I have been having this issue as well. Multiple rendering windows opening up. Currently using Blender 2.93.1 I am not using Chinese interface. I am using English.

Hi @Harley , is it safe to add your fix in blender-v2.93-release branch? Same issue reported recently (#90937) from 2.93 branch build

@PratikPB2123 - is it safe to add your fix in blender-v2.93-release branch? Same issue reported recently (#90937) from 2.93 branch build

Yes, but let me be pedantic for a moment as there are two similar but different issues.

This issue in this particular bug report only affects non-English Windows users. It is caused because our Windows-specific code to read the titles of the windows did not work correctly for non-English text. That was fixed with this: https://developer.blender.org/rBb39d66adde52eb72bd93c2ecd75135fdfc9ca05b and if this was only committed to the 3.0 branch then it could backported to 2.93. I only say "if" because I'm not exactly sure - I just committed to whatever was master at the time.

#90937 is indeed the same issue. It is Windows, Chinese, and 2.93 so I guess that does have to be backported.

But https://developer.blender.org/T88755 is a different issue. It affects all users but is only about saving and restoring a blend file that has an open Render window, which means you can get one extra. This is because all the windows that are restored during loading get the same "Blender" name.

I talked to Jeroen and this is now on his list of possible backports to 2.93
