OpenGL plugins show up as red until resized

[unplugred]

JUCE version is 8.0.2 because opengl support is even more broken in 8.0.3+

Nothing much to say, ui is just red.
Example of one such plugin that replicates the problem: https://github.com/unplugred/vsts/blob/main/plugins/mpaint/source/editor.cpp

Well we put the red there to find problems with paint and parenting and it seems we succeeded!

if you resize it works yeah? I wonder if theres some force-action-after-reparent we need. Or if we need to explicitly resize a child in OpenGL world.

It will be a few days until i can get to a windows box to test, by the way. But if you want to know where the red is it is here:

clap-juce-extensions/src/wrapper/clap-juce-wrapper.cpp

Line 2019 in d3bc57b

void paint(juce::Graphics &g) override { g.fillAll(juce::Colours::red); }

and that's the component which is the base component in the reparent hierarchy in the wrapper.

Thank you so much! Yes the red disappears when resized.
For now I downgraded to JUCE7 and everything appears to be working fine.
Additional info is that the problem was replicated in JUCE 8.0.4, and was replicated in both Reaper and Bitwig

Having the same issue. The clap version of the plugin flashes red on startup. Not visible in standalone or vst.

Using juce 8.0.6 and clap-juce-extension 4f33b4930b6af806018c009f0f24b3a50808af99.
