@lilhill Hi, we already implemented support for snapping time to reftime (where real data ends and nowcast starts) in radar and satellite layers. However, it will be available in version 51+ (not in the following v51). We are not planning to add a completely new button.

@compasscard Hi, this is intended behaviour since isolines are forecast and radar (satellite) is observation. Previously, we completely disabled the option of having isolines in radar and satellite layers, but after some complaints, we added them back. Since it does not make sense to combine forecast with past data (the mentioned -6h radar loop), it is indeed visible only in the last few minutes.

@Aziztibba It should be fixed now.

@Aziztibba Thank you for the additional info (regarding the problematic region), we already found the issue and a fix is on the way.

@Aziztibba Hi, thank you for the report. Could you tell us more info about your device? Also, does it happen only on satellite layer?
Thank you!

@fhawkings Hi, which type of animation is freezing? Is it radar / satellite animation, or some other layer animation?

@jab8283 Hi, this is a precipitation type in radar - the same case as snowflakes. For now, we have three categories - snowflakes for snow, no pattern for rain, and black dots for hail. In case you are not interested in displaying pType in radar, you can disable it in settings.

@Bulent-Bilgic Hi, thank you for the report. Could you send us screen recording of the app? We never saw this kind of error, so it could help us understand it. Thank you!

@NurlG Hi, we are already working on this - the pattern size just needs to be tweaked. It should be fixed in the next version.

@Nick-Eischens Hi, thank you for the report, we will fix this in the upcoming version.

@LordOfTheHornets Hi, playing animation combining past and forecast can be toggled in the desktop mode using play with forecast switch.

However, it is not possible in the mobile version, at least for now. Afaik, there was never an option to play both in the mobile version (neither in the old version of the radar GUI).

@robembury Hi, what device do you use? We tested the behaviour on multiple devices, and this error occurred only on devices Pixel 10, Pixel 10 Pro, and Pixel 10 Pro XL in combination with Android 16. It seems there is some SW/HW problem leading to WebGL crashes. We will try our best to find an alternative solution to fix it, but keep in mind that the source of the problem is not Windy, and it could only be resolved with a new OS version/patch.

@EdGi1 Hi, this issue is likely related to how your browser decodes input images (it is not a WebGL error). In case it applies some modifications to the image (like color space modification), it can result in the "checkerboard" artifacts.

Could you try another browser (like Google Chrome)? Also, updating the browser could resolve the problem.

Or you can try the following approach related to color profiles in Firefox:

@lstew452 Hi, could you send us screenshot of the error?

@Thexodus Hi, could you tell us why WebGL is a bad choice, specifically in combination with Android devices? Is it based on your personal experience? And what alternative do you recommend?

Btw, rewriting the whole renderer would not take us a day (even with agent mode).

@AlanTheBeast Hi, we already discussed with colleagues about this topic (whether to extrapolate when smooth animation is turned off). Both approaches make sense in their way, but in the end, we'll probably implement it in the future :)

@AlanTheBeast Hi, the reason why the futurecast is not working for you is because of Smooth radar and satellite animation setting is turned off (you can change this in settings). The current implementation does not support extrapolation when smooth animation is turned off.

@AlanTheBeast
Hi, thank you for the report. Could you answer us a few questions on that?

• Does it happen every time you open the radar overlay?
• Does it also happen in the satellite overlay (either with radar data (you need to enable it via overlay with radar) or even with satellite data)
• What MacOS and Safari versions are you using?
• Could you send us a short video, where you drag the timebox from past to future, so we can see, what actually happens?

Thank you very much!

@MetalAnon Hi, since the error appeared after updating the iOS version, and the version 18.7.2 (RC) is not a stable version, there is a high chance that something related to WebGL got messed up by Apple in that version. We cannot do much about it :/ We always recommend using stable OS versions to prevent these problems.

@MetalAnon
Hi, could you tell us what iOS version and what Apple device you are using? Does the error happen every time you open radar layer? Does it also happen on the satellite layer?

Thank you!
