The iGPU is nothing much, but I thought I'd read some visual novels on it (both are free demo versions, both sites are potentially NSFW, which is why I linked the demos directly, too:
- MUSICUS! | direct link
- Yonagi | direct link [may not be stable] -- filenames are in Shift-JIS, extract using unzip -O Shift-JIS or similar
Both require the locale to be set to ja_JP.UTF-8 for text to display properly, though it shouldn't matter for testing if touches register as mouse clicks in-game. MUSICUS!'s menu is English, the Yonagi demo has a launcher, just press the biggest button.
Using the keyboard+touchpad attachment, everything is fine, but tapping on the screen will only move the mouse cursor, it won't register as a click. I tried X11 and Wayland (and both DXVK and Gallium9 -- vanilla WINED3D works best), and there were certainly differences, just not as far as the taps not registering went.
Before I go down the rabbit hole of filing a bug I wanted to ask if touch not working was common knowledge, e.g. if there's a regression, or if it needed tweaks ...
