Buggy rendering in voice/video call UI on Windows arm64

[jenatali]

Steps to reproduce

1. Install the OpenCL™, OpenGL®, and Vulkan® Compatibility Pack
2. Log in to an account
3. Enter a voice or video call, with a single person or in a group.
4. Observe flicking / partially missing buttons.

Expected behaviour

The UI should work correctly.

Actual behaviour

For more context, I'm a developer for the GL driver that's mentioned in that log. This is the GL stack that's used for Windows on ARM64, when that compatibility pack is installed. This issue was forwarded my way but I'm pretty sure this is a bug higher in the stack. When I tried to debug, it looks like the only usage of GL here was sending fully-rendered already broken images down to the GL stack. I also tried dropping in other GL drivers.

Note that the issue doesn't reproduce if there's no GL driver available. This issue doesn't reproduce through the versions that are shipped for x64, I presume since those are using an older version of Qt with ANGLE (based on skimming this repo and its history). I haven't tried building it myself, so that I could use Qt 6 on x64 to isolate the CPU architecture aspect of it.

It's unclear if this is a Telegram bug or a Qt bug, but it's probably not my bug. If necessary, we can look at preventing this GL driver from being used for Telegram, but I'd prefer to wait until you've had a chance to take a look.
